[3,3,2,1,3]) and we need to figure out what is the lowest amount of deletions we need to make in order for all the elements to be the same. Question: Given an array of n elements. And return -1 if it is not possible to equalize. Delete a minimal number of elements from an array so that all elements of the modified array are equal to one another. Shift all the elements one by one one position to the left. Example 1 : Vector arr{64,32,16}; Division parameter=2. For instance, given the array , is between two subarrays that sum to . Code your solution in our custom editor or code in your own environment and upload your solution as a file. Objective Today, we're learning about the Array data structure. Given an array of integers, the task is to count minimum number of operations to equalize the array (make all array elements same). Examples: Input : stack1[] = { 3, 10} stack2[] = { 4, 5 } stack3[] = { 2, 1 } Output : 0 Sum can only be equal after removing all elements from all stacks. Remember, you can go back and refine your code anytime. The problem states that we’ll be gettin g an array as an input (e.g. – The elements of the first array are all factors of the integer being considered – The integer being considered is a factor of all elements of the second array. ByPasindu Piumal August 14, 2020 0. Arrays - DS . Please use list comprehensions rather than multiple loops, as a learning exercise. Equalize the Array | HackerRank.
