i solved uva 568 to find out the last non zero digit of n! and got accepted. here is my code #include<stdio.h> #define max 20000000 #define lmt 4473 unsigned flag[max>>6]; #define ifc(n) (flag[n>>6]&(1<<((n>>1)&31))) #define isc(n) (flag[n>>6]|=(1<<((n>>1)&31))) int power(int prime,int n) { int a=n;...

i am getting WA ,,, but failed to find out what is the wrong!! :roll: #include<stdio.h> #include<string.h> #include<string> #include<algorithm> #include<iostream> using namespace std; int main() { char str[20000],temp[20000]; int i,j=0; while(scanf("%c",&str[0])==1) { j=0; int p=0; if(str[0]!=' '&&s...

oh.i didnt notice it . but my compiler was always giving correct output for sample input while other compilers were not!

thanx a lot

why WA? couldnt find out!! :roll: my code- #include<stdio.h> #include<math.h> int divisor(int n) { int i,div; double sqrtn; if(n==1) return 1; else if(n==2) return 2; else{ div=2; sqrtn=sqrt(n); for(i=2;i<sqrtn;i++) { if(n%i==0) { div=div+2; } } if(sqrtn*sqrtn==n) div++; return div; } } int main() {...

thanx brianfry ..thanx a lot.is the cuberoot the cause?

i add 0.0003 with the double value. but i am still getting WA. i have also tried with float. i tested my code for all the values from 1 t0 10000.plz,brianfry..tell me if the algorithm is ok! if its not then why?! and how can i improve this? after adding 0.003 here is my new code- plz help me [removed]

Sorry

Hi brianfry, for 631 my output is 15 14

plz...Help me

i am just a beginner
