You can drive the solution equation by using a little bit of mathematics. Put the 0th element stored in the temporary variable at the last position in the array. Example. An array is a type of data structure that stores elements of the same type in a contiguous block of memory. You can equalize the elements by dividing the array elements from division parameter only. Here first we will sort the Array so that we can easily get the difference. His challenge is to find an element of the array such that the sum of all elements to the left is equal to the sum of all elements to the right. Hence, for a given element A, there will be at least A - Min(Array) moves to get to the solution. I have solved this in O(n) time and all the test cases got passed.
