    Here is my simple c++ solution, video explanation here : https://youtu.be/xwLiYvExM6I

    string twoStrings(string s1, string s2) {
    map<char, int>mp;
    for(int i = 0; i < s1.size(); i++) mp[s1[i]] = 1;
    for(int i = 0; i < s2.size(); i++){
        if(mp[s2[i]]) return "YES";
    }
    return "NO";
}

    My solution is partially correct:

    def twoStrings(s1, s2):
    # Write your code here
    msg = 'NO'

    for cs1 in s1:
        for cs2 in s2:
            if cs1==cs2:
                msg = 'YES'
    return msg

    Using c#

    public static string twoStrings(string s1, string s2)
{
  HashSet<char> hashS1 = new HashSet<char>(s1);

  foreach(char c in s2) {
	if (hashS1.Contains(c)) {
	  return "YES";
	}
  }
  return "NO";
}

    short solution:

    def twoStrings(s1, s2):
    # Write your code here
    myset = set()
    flag = 'NO'
    
    for i in range(len(s1)):
        myset.add(s1[i])

    for i in range(len(s2)):
        if s2[i] in myset:
            flag = 'YES'
            break

    return flag

    for Python3 Platform

    def twoStrings(s1, s2):
    for i in s1:
        if (i in s2):
            return "YES"
    else:
        return "NO"

p = int(input())
for j in range(p):
    s1 = input()
    s2 = input()
    
    result = twoStrings(s1, s2)
    
    print(result)
