Welcome to the daily solving of our PROBLEM OF THE DAY with Kunal Jain We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Arrays but also build up problem-solving skills.
Given an array arr[ ], your task is to find the minimum number of increment operations required to make all the elements of the array unique. i.e.- no value in the array should occur more than once. In one operation, a value can be incremented by 1 only.
Examples :
Input: arr[] = [1, 2, 2]
Output: 1
Explanation: If we increase arr[2] by 1 then the resulting array becomes {1, 2, 3} and has all unique values.Hence, the answer is 1 in this case.
Give the problem a try before going through the video. All the best!!!
