Minimum characters required to be removed to make frequency of each character unique | Function to find the minimum count of characters required to be deleted to make frequencies of all characters unique.
Stores frequency of each distinct character of str.
Store frequency of each distinct character such that the largest frequency is present at the top.
Stores minimum count of characters required to be deleted to make frequency of each character unique.
Traverse the string.
Update frequency of str [ i ].
Traverse the map.
Insert current frequency into pq.
Traverse the priority_queue.
Stores topmost element of pq.
Pop the topmost element.
If pq is empty.
Return cntChar.
If frequent and topmost element of pq are equal.
If frequency of the topmost element is greater than 1.
Insert the decremented value of frequent.
Update cntChar.
Driver Code.
Stores length of str"
How can the above be solved in Python?
 Write me a code to minimum characters required to be removed to make frequency of each character unique and the other steps required?
