Process
Online assessment: Five code questions with four medium difficulty levels and one easy level question. This includes Backtracking, DFS, BFS, and Dynamic Programming (DP) problems. You need to finish within 2 hours, which is not easy.
Questions
In an array, arr, the elements at indices i and j (where i < j) form an inversion if arr[i] > arr[j]. In other words, inverted elements arr[i] and arr[j] are considered to be "out of order".
To correct an inversion, we can swap adjacent elements.
