303. Range Sum Query - Immutable.py

# Given an integer array nums, handle multiple queries of the following type:

# Calculate the sum of the elements of nums between indices left and right inclusive where left <= right.

class NumArray:

    def __init__(self, nums: list[int]):
        self.nums = nums

    def sumRange(self, left: int, right: int) -> int:
        return sum(self.nums[left:right+1])
        


# Your NumArray object will be instantiated and called as such:
# obj = NumArray(nums)
# param_1 = obj.sumRange(left,right)
