Day 25 of 100 days of code

Today, I successfully tackled two CodeChef problems.

question 1

#include <bits/stdc++.h>
using namespace std;

bool solve(int n){
  int sum=0;
  for(int i =0;i<n;i++){
    int x;
    cin>>x;
    sum+=x;
  }
  return (sum%2==1);
}
int main(){
  int t;
  cin>>t;
  while(t--){
    int n;
    cin>>n;
    if(solve(n)){
      cout<<"YES"<<endl;
    }else{
      cout<<"NO"<<endl;
    }

  }
}

question 2

#include <bits/stdc++.h>
using namespace std;

bool solve(string a,string b){
  int x = count(a.begin(),a.end(),'1');
  int y = count(b.begin(),b.end(),'1');
  return x==y;
}
int main(){
  int t;
  cin>>t;
  while(t--){
    int n;
    cin>>n;
    string a;
    cin>>a;
    string b;
    cin>>b;
    if(solve(a,b)){
      cout<<"YES"<<endl;
    }else{
      cout<<"NO"<<endl;
    }

  }
}
