You are given an integer array, nums, and you need to handle multiple queries of the following type:
Query: Calculate the sum of elements in nums between indices i and j (inclusive), where i <= j.
Implement the NumArray class to support the following operations efficiently:
Constructor: Initializes the object with the integer array nums.
sumRange(i, j): Returns the sum of the elements of nums between indices i and j (inclusive), i.e., the sum of nums[i] + nums[i + 1] + ... + nums[j].
Constraints:
nums.length
nums[i]
i
