2919. Minimum Increment Operations to Make Array Beautiful

Leetcode Solutions

Initialize a DP array dp with a size equal to the length of nums and fill it with -1, representing uncomputed states.
Define a recursive function solve that takes the current index i and the array nums.
If i is greater than or equal to the length of nums minus 2, return 0, as there are no more subarrays of size 3 to consider.
If dp[i] is not -1, return dp[i] as the already computed result.
Compute the minimum increments needed if we choose to increment the current element (i), the next element (i+1), or the element after that (i+2).
Store the minimum of these three values in dp[i] and return it.
In the main function, iterate over nums and replace each element with the maximum of k - nums[i] and 0. This represents the minimum increments needed to make the single element beautiful.
Call the solve function starting from index 0, 1, and 2, and return the minimum of these three calls.
