Multiple Queries using array nums

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

Update the value of an element in nums.

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

**Input
**["NumArray", "sumRange", "update", "sumRange"]
[[[1, 3, 5]], [0, 2], [1, 2], [0, 2]]
**Output
**[null, 9, null, 8]

class NumArr(object): def __init__(self,nums): self.nums=nums def update(self,index,val): self.nums[index]=val def sum1(self,i,j): self.sum=0 for k in range(i,j+1): self.sum+=self.nums[k] return self.sum #getting the input numarr,sumr= list(map(int,input('Num : ').split(','))),list(map(int,input('sumR : ').split(','))) update=list(map(int,input('Update : ').split(','))) rang=list(map(int,input('SRange : ').split(','))) #creating obj obj1=NumArr(numarr) x=obj1.sum1(rang[0],rang[1]) obj1.update(update[0],update[1]) y=obj1.sum1(rang[0],rang[1]) print([None,x,None,y])

**Input_1:**

Num : 1,3,5

sumR : 0,2

Update : 1,2

SRange : 0,2

**Output:**

[None, 9, None, 8]

**Input_2:**

Num : 1,2,3,5,6,7,8

sumR : 0,5

Update : 5,10

SRange : 0,6

**Output:**

[None, 32, None, 35]
