Give me a code to minimum number of distinct elements after removing M items and the other steps required given the following:
Minimum number of distinct elements after removing M items | Set 2 | Function to return minimum distinct character after M removals.
Count the occurences of number and store in count.
Count the occurences of the frequencies.
Take answer as total unique numbers and remove the frequency and subtract the answer.
Remove the minimum number of times.
Return the answer.
Driver Code.
Initialize array.
Size of array.
Function call"
How can the above be solved in Python?
