The hardest part about this problem is to understand what is it actually saying. Insight 2: given a certain element A, and using "Insight 1", in order for all the elements to be the same at the end, inevitably we'll have to transform A into the minimum element in the array. Shift all the elements one by one one position to the left. Monday, October 31, 2016. Watson gives Sherlock an array of integers. In fact the solution will then be the summation of Ai - Min(Array) for every Ai in the array. You can equalize the elements by dividing the array elements from division parameter only. (Element\ in\ array) - (Number\ to\ find) = target\ value; Since the array is sorted, use binary search to find the element in the sorted array. And return -1 if it is not possible to equalize. The array may not be reordered. Example: Input: n1[] = {3, 2, 1, 1, 1} n2[] = {4, 3, 2} n3[] = {1, 1, 4, 1} Output: 5. 4 of 6; Test your code You can compile your code and test it for errors and accuracy before submitting.
