`You are given an array(of integers) of length n.You are required to answer q queries.Queries can be of two types0. 0 ind : In this you have to tell the value of arr[ind].1. 1 l r val: In this query u have to increase all elements in this interval [l, r] by val.To do the above task u have to create a datastructure as follows :-Implement the SegmentTree class:1. SegmentTree(int arr[]): Initializes the SegmentTree object with an array,2. void update(int l, int r, int val): increase all elements in this interval [l, r] by val,3. int query(int ind): return arr[ind].`
Input Format
