Minimum increment and decrement by K of each pair elements required to make all array elements equal | Function to check if its possible to make all array elements equal or not ; Stores the sum of the array ; Traverse the array ; If sum is divisible by N ; Otherwise , not possible to make all array elements equal ; Given array ; Size of the array
