normal way is int main(){ int a=2000,count=0,temp; while(a!=0) { temp=a%10; if(temp==0) count++ else break; a/=10; } printf("%d",count); } is there more efficient way ? for 32-bit integer (maximum value 2147483647) need maximum of 4 tests. 64 bits add 1 more test 16 zeros. start larger powers of 10 , work down: int counttrailingzeros(int n) { int zeros = 0; if((n % 100000000) == 0) { zeros += 8; n /= 100000000; } if((n % 10000) == 0) { zeros += 4; n /= 10000; } if((n % 100) == 0) { zeros += 2; n /= 100; } if((n % 10) == 0) { zeros++; } return zeros; } this has better worst-case performance, if 9/10ths of numbers pass have no trailing zeros average case worse. depends on values passing in typical case. however, if 9/10ths of numbers pass have no trailing zeros shouldn't worry optimizing original code in first pla

can please take @ this demo , let me know why change() function not able slidedown() hidden element in bootstrap 3? here code have $(function() { $('input:radio').change(function() { if($(this).val()== 'dog') { $('#hidden-list-1').slidedown(); } if($(this).val()== 'bird'){ $('#hidden-list-2').slidedown(); } }); }); as other answers have mentioned issue boostrap has style .hidden{ display: none !important; } one way solve removing hidden class. $('#hidden-list-1').hide().removeclass('hidden').slidedown(); here demo https://jsfiddle.net/dhirajbodicherla/zzdl5jp7/3/

this question has answer here: is there more interface having correct methods 17 answers you can define compareto method in class without implementing comparable interface. benefits of implementing comparable interface? the benefit of implementing interface methods require object implements comparable interface. gives them guarantee object you're passing has compareto method correct signature. there's no way in java have method require object implement given method (such compareto ) in , of itself. around this, interfaces created. time have object know comparable , know can call compareto on it.

i'm using google sheets. have spreadsheet has horizontal row of dates @ top. i'm attempting search horizontal date row today, , return value of cell vertically below header. if today's date found in "h1" return value of "h24", if today's date found in "y1" return value of "y24" etc , on. i've tried =vlookup , =hlookup , can't , semblance of results aren't error. any @ appreciated, i'm excel/sheets novice. does formula work want: =filter(a24:z24,a1:z1=today()) if current data in cell h1 formula should output contents of cell h24

i have joined ios develepors world. have questions. i don't understand auto layout scrollview. im tried every kind method everytime seen different size , different location (button). i want create scrollview (hortizonal) on 12 buttons iphone models. should do? write details. thank much. it's pretty easy, have methodic constraints add. start outside constraints , start adding inner ones. check out tutorial wrote implementing uiscrollview + auto layout in swift. if have doubt, ask me :) https://www.dribba.com/blog/2015/07/21/scrollview-autolayout-ios8-swift/

hey guys have function, gives me error when test it. have idea on how fix exercise. please read through. write function cyclelength(array), returns number of students form loop, given start talking left-most one. input array list of non-negative integers, such array[m] number of student whom student m redirects. no student redirects himself. left-most student number 0, next number 1, , on. each element in list in range [0, n-1] n length of list. example, suppose list [1, 3, 0, 1]. student 0 redirects student 1, redirects student 3, redirects student 1. there loop of 2 students: 1, 3. answer 2. note though started student 0, not part of loop. here function: def cyclelength(m): lst = [] = 0 while not in lst: lst.append(i) = int(m[i]) b = len(lst) - lst.index(i) return b you got right. >>> def cyclelength(students): ... seen = [] ... current = 0 ... # run till have seen students ... while len(seen) != len(st

i need develop c# application using **backgrounworker** , without using windows forms . i've seen examples presented microsoft regarding use of backgrounworker class, , they're developed windows forms. can use backgroundworker without windows forms ? if so, please provide detail. in advance ! in c# there can use tasks or threads both used run in background in separated execution context ( separated thread ) this simple example using thread using system.threading; // creating new thread , pass delegate run thread thread = new thread(new threadstart(workthreadfunction)); // command start thread thread.start(); public void workthreadfunction() { // background work }

so far, understand these spaces define aspect of games' 3d world. view space camera, , define creating matrix contains camera position, camera target , "up" direction of camera. this done in code follows... xmmatrix cameraview; xmvector cameraposition; xmvector cameratarget; xmvector cameraup; /* describing matrix */ cameraposition = xmvectorset(0.0f, 0.0f, -0.5f, 0.0f); cameratarget = xmvectorset(0.0f, 0.0f, 0.0f, 0.0f); cameraup = xmvectorset(0.0f, 1.0f, 0.0f, 0.0f); /* creating matrix*/ cameraview = xmmatrixlookatlh(cameraposition, cameratarget, cameraup); i have hard time trying visualize in head. in simple terms.. "enabling" player move around @ creating cameraview ? (assuming 3d world created) can explain me happening here first suggestion: new directxmath , direct3d, should take @ directx tool kit , simplemath wrapper in particular. save lot of distraction here. when render object, there

is advisable give bootstrap 3 classes non-block level elements such span? best practices in area? still see answer question anywhere. since bootstrap classes specifies css properties listed below, technically possible use them on non-block elements, have additionally set display: block; these elements. don't think advisable, html elements must used taking in account of purpose, described in html w3c standard. for .row: margin-left margin-right for col-xx-xx: position min-height padding-left padding-right width

i want put in elements in vector. till date have used way of inserting elements in vector , has worked. not know why not working today. world::world() { collisionmap.loadfromfile("collisionmap.png"); for(int i=0; i<collisionmap.getsize().y; i++) { for(int j=0; j<collisionmap.getsize().x; j++) { if(collisionmap.getpixel(j,i)==sf::color(0,0,0)) { cout<<"test"<<endl //prints collisionlist.push_back(sf::floatrect(j*32, i*32, 32, 32)); } } } cout<<collisionlist.size(); //shows nothing } edit: i forgot mention :- 1.i using sfml. 2. collisionlist vector. 3.this code compiles without problem. 4.the size of collisionmap not 0 since collisionmap.getsize() returns accurate value. cout<<collisionlist.size(); //shows nothing of course. puts stuff in buffer, doesn't output anything. try: cout<<

in fortran there statement implicit none throws compilation error when local variable not declared used. understand python dynamically typed language , scope of variable may determined @ runtime. but avoid unintended errors happen when forget initialize local variable use in main code. example, variable x in following code global though did not intend that: def test(): y=x+2 # intended x local variable forgot # x not initialized print y x=3 test() so question that: there way ensure variables used in test() local , there no side effects. using python 2.7.x. in case there local variable, error printed. so question that: there way ensure variables used in test() local , there no side effects. there technique validate globals aren't accessed. here's decorator scans function's opcodes load_global . import dis, sys, re, stringio def check_external(func): 'validate function not have global lookups' saved_st
