Make Array Elements Equal
Consider ARR = [3, 4, 5] now suppose if we want to change every element value to 4, then the cost of changing 3 to 4 is |3 - 4| which is 1, and the cost of changing 5 to 4 is |5 - 4| which is 1, so the total cost is 1 + 1 = 2. The value 2 is the minimum cost to make all values in the array equal. Hence, the answer is 2.
The first line of the input contains an integer ‘T’ denoting the number of test cases. The first line of each test case contains a single integer, ‘N’, denoting the number of elements in the array. The second line of each test case contains 'N' space-separated integers denoting the elements of the array.
For each test case, print the minimum cost to make elements of the array equal. Print the output of each test case in a separate line.
1 <= T <= 5 1 <= N <= 10^5 1 <= ARR[i] <= 10^8 Time limit: 1 sec
