Given an array, choose two contiguous non-overlapping arrays, such that all elements are strictly increasing. Return the maximum length possible for this combination. Ex: 7 1 2 4 6 5 3 8 9 10 => ans: 7 (Choose 1 2 4 6 & 8 9 10) l
Input: A = [0,6,5,2,2,5,1,9,4], L = 1, M = 2 Output: 20 Explanation: One choice of subarrays is [9] with length 1, and [6,5] with length 2. Add solution -
