What is a code to maximize the sum of selected numbers from an array to make it empty and the other steps required given the following:
Maximize the sum of selected numbers from an array to make it empty | function to maximize the sum of selected numbers.
maximum in the sequence.
stores the occurrences of the numbers.
marks the occurrence of every number in the sequence.
ans to store the result.
Using the above mentioned approach.
if occurence is greater than 0.
add it to ans.
decrease i - 1 th element by 1.
decrease ith element by 1.
decrease i.
Driver code"
How can the above be solved in Python?
