The existence of array [1] and array [3] does not imply the existence of array [2]. JavaScript 's native Array object has methods Array .slice (), to extract a set of contiguous elements from an array, and Array .splice () to remove some contiguous elements and, optionally, replace them with others. Hackerrank - Array Manipulation Solution. Starting with a 1-indexed array of zeros and a list of operations, for each operation add a value to each of the array element between two given indices, inclusive. Once all operations have been performed, return the maximum value in your array. For example, the length of your array of zeros.
