Maximize Points After Choosing K Tasks

Description

You are given two integer arrays, technique1 and technique2, each of length n, where n represents the number of tasks to complete.

- If the ith task is completed using technique 1, you earn technique1[i] points.

- If it is completed using technique 2, you earn technique2[i] points.

You are also given an integer k, representing the minimum number of tasks that must be completed using technique 1.

You must complete at least k tasks using technique 1 (they do not need to be the first k tasks).

The remaining tasks may be completed using either technique.

Return an integer denoting the maximum total points you can earn.
