* [307] Range Sum Query - Mutable * * Given an integer array nums, find the sum of the elements between indices i and j (i ≤ j), inclusive. * * The update(i, val) function modifies nums by updating the element at index i to val. * * Example: * * * Given nums = [1, 3, 5] * * sumRange(0, 2) -> 9 * update(1, 2) * sumRange(0, 2) -> 8 * * * Note: * * * The array is only modi
