Longest contiguous subarray with one substitution
Given an array { 1, 7, 7, 2,3, 7, 6,-20}. Find the longest nondecreasing contiguous sequence with substitution. we can substitute any array element with any integer such as all occurences of 7 replaced with 1. In this way new array would be { 1,1,1,2,3,1,6,-20}. Only one substitution is allowed.
What can be the optimal solution for this?
Can someone help me with the approach?
