TOTR:WRONG ANSWER

THE CODE RUNS FINE FOR TEST CASES..

#include <iostream>
#include <cstdlib>
#include<cctype>
#include<cstring>
using namespace std;
int main ()
{
    int t;
    char m[26];
    char strabc[]="abcdefghijklmnopqrstuvwxyz";
    char strABC[]="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    scanf("%d%s",&t,m);
    while(t--)
    {
        char a[100];
        scanf("%s",a);
        //cout<<"a= "<<a<<endl;
        for(int i=0;i<strlen(a);i++)
        {
            if(a[i]>=65 &&a[i]<=90)
            {
                for(int j=0;j<26;j++)
                {
                    if(strABC[j]==a[i])
                    {   printf("%c",m[j]-96+64);
                        //cout<<endl<<"m[j]= "<<m[j]<<endl;
                        //cout<<"j="<<j<<endl;
                        //cout<<"strABC[j]="<<strABC[j]<<endl;
                    }
                }
            }
            else if(isalpha(a[i]))
            {
                for(int j=0;j<26;j++)
                {
                    if(strabc[j]==a[i])
                        printf("%c",m[j]);
                }
            }
            else if(a[i]=='_')
                    printf(" ");
            else
                printf("%c",a[i]);
        }       
        printf("\n");
}
  return 0;
