In the registration system problem from Code forces beta round #4 it is given that the number of character in a string are not more than 32.but when i use a string of size exactly 32 character i get a wrong answer on 13 test case.and if i use s[33] my solution is accepted.can i know where I am going wrong ~~~~~ Your code here... ~~~~~

include<stdio.h>

include<string.h>

int main(){ int n,i,j,l=0; scanf("%d",&n); int b[1000000]={0}; char s[33],a[n][33]; for(i=0;i<n;i++){ scanf("%s",s); for(j=0;j<l;j++){ if(strcmp(a[j],s)==0){ b[j]++; break; } } if(j>=l){ l++; printf("OK\n"); strcpy(a[j],s); } else{ printf("%s%d\n",s,b[j]); }

}
return 0;
