How to check a partial similarity of two strings in C# -

-
is there function in c# check % of similarity of 2 strings? for example have: var string1="hello how doing"; var string2= " hi, how you"; and function(string1, string2) will return similarity ratio because words "how", "are", "you" present in line. or better, return me 60% of similarity because "how", "are", "you" 3/5 of string1. does function exist in c# that? a common measure similarity of strings so-called levenshtein distance or edit distance . in approach, defined set of edit operation defined. levenshtein distance minimum number of edit steps necessary obtain second string first. closely related damerau-levenshtein distance , uses different set of edit operations. algorithmically, levenshtein distance can calculated using dynamic programming , can considered efficient. however, note approach not take single words account , cannot directly express similarity in percent.

javascript - Call order with frames involved -

-
i have html page embedded iframe. possible reference global variable @ window.top without prefix (window.top or similar), or 1 have use full path access variable embedded frame. in quick test in google chrome not access variable @ window.top level without prefix, have sneaking suspicion has been possible earlier/in other browsers/in situations. question is: if there no variable sought name in iframe's local scope (the iframe's contentwindow), browser (some browsers?) automatically @ next higher level (the parent level window can belong frame/iframe or window.top) , return value/object? and: if there duplicate variable names @ local embedded iframe level , parent level, local level win out or can there situations the window.top version gains precedence? if there no variable sought name in iframe's local scope (the iframe's contentwindow), browser (some browsers?) automatically @ next higher level (the parent level window can belong frame/iframe or window.

c - The scanf function is accepting values infinately -

int n; int a[maxsize]; int b[maxsize]; int c[maxsize]; int i; printf("enter number of elements(disks)\n"); scanf("%d",&n); printf("enter elements in ascending order\n"); for(i=0;i<n;i++) { scanf("%d",&a[i]); } this works fine @ times, of times piece of code going infinite loop,the 'scanf' in loop accepting values infinitely,i tried using function (fflush) clear buffer contents,but still not working, please me out!! , please explain why !! the code posted cannot enter infinite loop, it's probable scanf() function blocking until input ctrl+d end input stream or maybe integer, problem handling input in dangerous way because not checking errors @ all, might want this #include <stdio.h> #include <stdlib.h> #define clearstdin() {int chr; while (((chr = getchar()) != eof) && (chr != '\n')); } while (0) #define somelargesize 1024 int main(void) { unsigned int index;

Python for loop only saves the last loop in my 2-d array -

i producing 1 dimensional random walks , want loop save maximum distance origin has been reached far, time progresses. 5 random walks produced. code: for j in range(5): r = rand(10000) t = range(10000) x = zeros(10000) y = zeros((10000, 5)) in range(10000): walk = r[i] if walk < 0.5: x[i] = x[i-1] - 1 y[:,j]= maximum.accumulate(abs(x)) else: x[i] = x[i-1] + 1 y[:,j]= maximum.accumulate(abs(x)) plot(t,x, label="walk %d" %(j+1)) title("1-d random walk (position versus time)") xlabel("time") ylabel("position") legend(loc="best") grid() the problem after loop iterates on set range (5) output 2-d array includes last iteration. somehow, overwhites previous ones, 10000x5 array last row filled in. how can make work? you've, reason, chosen execute y = zeros((10000, 5)) over , on again, each time through outer loop. as

python - readlines will always block the caller -

-
i'm reading programming python mark lutz, , came across bit: for pipe objects, effect of iterators may more useful avoiding loading entire result memory @ once: readlines block caller until spawned program finished, whereas iterator might not. what mean? if consider subprocess.popen example. if call command outputs lot of data subprocess.pipe calling proc.stdout.readlines() wait until command finishes. where if use iter for line in iter(proc.stdout.readline,"") , see output in real time , avoid having store output in memory. if had process each line of output make more sense process line line input came in using iter allows opposed blocking until command terminates using readlines .

android - onNewIntent is not being called - only every second time? -

i have notification setting up intent intent = new intent(ctx, mainactivity.class); intent.setflags(intent.flag_activity_new_task | intent.flag_activity_no_history); pendingintent pi = pendingintent.getactivity(ctx, 0, intent, pendingintent.flag_update_current); mbuilder.setcontentintent(pi); mnotificationmanager.notify(mainactivity.notification_result, mbuilder.build()); when notification, mainactivity.onnewintent() getting called every second time reason. have debug log statement in there, , literally every 2nd time, log not trigger. any thoughts? i not sure requirements, onnewintent declare in docs this called activities set launchmode "singletop" in package, or if client used flag_activity_single_top flag when calling startactivity(intent). in either case, when activity re-launched while @ top of activity stack instead of new instance of activity being started, onnewintent() called on existing instance intent used re-launch it. s

f# - Parsing "x y z" with the precedence of multiply -

-
i'm trying write parser mathematica language in f# using fparsec. i have written 1 miniml supports syntax f x y = (f(x))(y) high precedence function application. need use same syntax mean f*x*y and, therefore, have same precedence multiply. in particular, x y + 2 = x*y + 2 whereas x y ^ 2 = x * y^2 . how can accomplished? as stephan pointed out in comment can split operator parser 2 separate parsers , put own parser in middle space-separated expressions. following code demonstrates this: #i "../packages/fparsec.1.0.1/lib/net40-client" #r "fparsec" #r "fparseccs" open fparsec open system.numerics type expr = | int of biginteger | add of expr * expr | mul of expr * expr | pow of expr * expr let str s = pstring s >>. spaces let pint : parser<_, unit> = many1satisfy isdigit |>> biginteger.parse .>> spaces let high = operatorprecedenceparser<expr,unit,unit>() let low = operatorprecedenceparser&l

ruby - Rails 4 + ActiveRecord: group_by on column from different model -

i have these models: class user < activerecord::base has_many :car_votes has_many :cars end class car < activerecord::base belongs_to :user has_many :car_votess end class gamevote < activerecord::base belongs_to :user belongs_to :car end if want display cars user voted (and group output day when user voted cars): @voted_cars = @user.car_votes.order('car_votes.created_at desc').group_by { |r| r.created_at.to_date } so on output cars user voted grouped days user voted games. but group output according car_votes.created_at , according cars.created_at . how this? thank in advance. if associations allow this(try on rails console): @c = carvote.first puts @c.car.created_at and return value rather error, can do: @voted_cars = @user.car_votes.order('car_votes.created_at desc').group_by { |r| r.car.created_at.to_date }

2d arrays, functions, C -

the problem write function takes 2 dimensional array, 2 integers represent number of rows , columns in array, , prints out 2 x 2 array represents largest square in array. largest square means square sum of elements greatest in array. given array: 1 2 3 4 5 6 7 8 9 10 11 12 output should be: 7 8 11 12 though never learned subarray/matrixes , kadane algorithm in class i've been online day , im hopping close solution? (*my professor interested in function, we're not supposed submit full program) due yesterday im lost, please if can , in advance! /*void f(x) opens file take in given array*/ void largestsqaure(int array[row][column]) { file*ifp= fopen("largestsquare.txt", "r"); file*ofp= fopen("output.txt", "w"); for(r0w= 0; row < size; row++) fscanf(ifp, "%d", &array[row]); /*declaring variables*/ int maxsum = int_min, finalleft, finalright, finaltop, finalbottom;
