Check if max occurring character of one string appears same no. of times in other
  • Difficulty Level : Basic
  • Last Updated : 06 Jan, 2020

Given two strings, we need to take the character which has the maximum occurrence in the first string and then we have to check if that particular character is present in the second string the same number of times as it is present in the first string.

Examples:

Input : s1 = "sssgeek", s2 = "geeksss"
Output : Yes
Max occurring character in s1 is
's'. It occurs same number of times
in s2.

Input :  geekyarticle
         gfggfggfg
Output : No

Store counts of characters in first string and find the maximum count. Now traverse through the second string and check if the maximum occurring character occurs same number of times or not.

Below program to illustrate the above problem

C++




// C++ program to check the problem
#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define ASCIISIZE 256
  
int match(string s1, string s2)
{
    // Create array to keep the count of individual
    // characters and initialize the array as 0
    int count[ASCIISIZE] = { 0 };
  
    // Construct character count array from the input
    // string.
    for (int i = 0; i < s1.length(); i++)
        count[s1[i]]++;
  
    // Count occurrences of maximum occurring character
    int mx_cnt = 0, mx_chr;
    for (int i = 0; i < ASCIISIZE; i++) {
        if (count[i] > mx_cnt) {
            mx_cnt = count[i];
            mx_chr = i;
        }
    }
  
    // look if that character is present, the same
    // number of times it is present in second string
    for (int i = 0; i < s2.length(); i++) 
        if (mx_chr == s2[i])
            mx_cnt--;
      
    // check if sum is greater or equal to number
    // return 1
    if (mx_cnt == 0)
        return 1;
}
  
// Driver program to test the above function
int main()
{
    string s1 = "geekforgeeks", s2 = "geekisgeeky";
    if (match(s1, s2))
        cout << "Yes ";
    else 
        cout << "No";
  
    return 0;
}

// Construct character count 
// array from the input string.
char []s3 = s1.toCharArray();
for (int i = 0; i < s3.length; i++)
    count[s3[i]]++;
  
// Count occurrences of 
// maximum occurring character
int mx_cnt = 0;
int mx_chr = 0;
for (int i = 0; i < ASCIISIZE; i++) 
{

    {
        mx_cnt = count[i];
        mx_chr = i;
    }
}
  
// look if that character is 
// present, the same number 
// of times it is present in
// second string
char []s4 = s2.toCharArray();
for (int i = 0; i < s4.length; i++) 
    if (mx_chr == s4[i])
        mx_cnt--;
  
// check if sum is greater or 
// equal to number return 1

    return 1;

        System.out.println("Yes ");
    else
        System.out.println("No");
