don't use namespace std here! And you will get Ac!

sorry but still WA#1

try avoiding \n in the end. At least my AC doesn't.

Have you fixed WA1 ?

I've go AC. WA#1 took place, cause there is some trash in input.
It's very very not fear for admins/judges not to warn about it in problem statement !

Got AC with reading a string, and WA#1 with symbol reading (commented block), but both ways of reading work correctly on my computer. It seems that input consists EOL symbol '\n'.

int main() {

    char c;
    int n=0;
    char sym[101];
    int code[101];

    scanf("%s",sym);
    n=strlen(sym);
    for (int i=0;i<n;i++) code[i]=sym[i]-0x61;

/*
    while (scanf("%c",&c)!=EOF) {
          code[n]=c-0x61;
          n++;
    }
*/
