Non-Decreasing Array Problem Statement

Given an integer array ARR of size N, determine if it can be transformed into a non-decreasing array by modifying at most one element.

An array is defined as non-decreasing if ARR[i]

Question

Given an integer array ARR of size N, determine if it can be transformed into a non-decreasing array by modifying at most one element.

An array is defined as non-decreasing if ARR[i] <= ARR[i + 1] for every index i where 0 <= i <= N - 2.

The first line contains an integer 'T' representing the number of test cases. For each test case, the input consists of:

For each test case, output "true" if the array can be made non-decreasing by modifying at most one element, otherwise output "false".

true
false

You do not need to print anything yourself. Implement the given function to solve the problem.

Accepted Answer

The solution checks if an integer array can become non-decreasing by modifying at most one element.

Iterate through the array and check if there are more than one decreasing pairs of elements.
If there are more than one decreasing pairs, return false.
If there is only one decreasing pair, check if modifying one of the elements can make the array non-decreasing.
If modifying the element at index i-1 or i can make the array non-decreasing, return true.
Otherwise, return false.
