Check if max occurring character of one string appears same no. of times in other

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.
