Hey @prashantverma.vn,

Your Output format is wrong.
In the sample output:
#1 : 2
#2 : 3
#3 : 5
The numbers after # specifies the number of iteration(or the ith test cases).

I have modified your code:

Give a like if you are satisfied.

#include<bits/stdc++.h>
using namespace std;
void compute(int n,string s,int &ans){
if(n==0){
ans++;
return;
}
if(n<0)
return;
compute(n-1,“a”+s,ans);
int x=s.length();
if(s[x-1]!=‘b’)
compute(n-1,“b”+s,ans);
return;
}
int main(){
int t;
cin>>t;
int i=1;
while(t–){
int n;
cin>>n;
int count=0;
compute(n,"",count);
cout<<"#"<<i++<<" : "<<count<<endl;
}
return 0;
}
