This code works perfectly. Try out with different test data. int main() { //char str[]="qwertyuioplkjhgfdsazxcvbnm"; char str2[] = "qwertyquejolpd"; int val, i; int len = strlen(str); int unique=1; int checker=0; for(=0;i<len;i++) { val = str[i]-'a'; if( (checker & (1<<val)) > 0 ) { printf("\nNo, there aren't unique."); unique=0; break; } checker |= (1<<val); } if(unique==1) printf("\nUnique charaters."); return 1; }
