One question per day for leetcode

The minimum increment that makes the array unique

Given the integer array A, each move operation will select any A [I] and increment it by 1.

Returns the minimum number of operations that make each value in A unique.

Example 1: input: [1, 2, 2, 2]

Output: 1 explanation: after a move operation, the array will become [1, 2, 3].

Example 2: input: [3, 2, 1, 1, 2, 1, 7]

Output: 6 explanation: after 6 move operations, the array will become [3, 4, 1, 2, 5, 7]. You can see that five or less move operations cannot make each value of the array unique.
