What is a code to maximum points covered after removing an Interval and the other steps required given the following:
Maximum points covered after removing an Interval | Function To find the required interval.
Total Count of covered numbers.
Array to store numbers that occur exactly in one interval till ith interval.
Calculate New count by removing all numbers in range [ l , r ] occurring exactly once.
Driver code"
How can the above be solved in Python?
