can anyone pls explain me why this code is not working for ques [B. Decode String](https://codeforces.com/contest/1729/problem/B) ↵
↵
while testing with the all 9 test cases(which is given in ques) this test case ↵
5↵
11111↵
is giving me wrong ans while testing it separately it is giving the right ans↵
↵
#include<bits/stdc++.h>↵
↵
using namespace std;↵
↵
typedef long long li;↵
↵
int main(){↵
↵
li t;↵
↵
cin>>t;↵
↵
string ans="abcdefghijklmnopqrstuvwxyz";↵
↵
while(t--){↵
li n;↵
cin>>n;↵
string s;↵
cin>>s;↵
string res="";↵
↵
for(li i=0;i<s.length();i++){↵
if( s[i+2]=='0' && s[i+3]!='0' && i<n){↵
res+=ans[(s[i]-'0')*10+(s[i+1]-'0'-1)];↵
i+=2;↵
}else{↵
res+=ans[s[i]-'0'-1];↵
}↵
