How to find the minimum number of increments/decrements needed to make all array elements distinct ?

Revision en6, by yamih23436, 2021-03-31 06:50:30

Say , size of given array is $$$N$$$ and $$$abs(a[i])$$$<= 10000000

Example :

$$$ {1,100,100,100,100} $$$

Minimum cost = $$$4$$$

$$${1,100,101,99,102}$$$

I am looking for both $$$O(n*n)$$$ and $$$O(n)$$$ solutions .

Source of the problem : Just occurred to my mind .

My idea : Sort the given array , then apply the algorithm mentioned in this problem : https://codeforces.net/contest/713/problem/C
