Discuss an effective approach to satisfy the requirements. (Pseudocodes not required) b) Consider the following numbers for constructing a segment-tree: Showing detailed steps, perform the following operations on a Segment Tree (Array index starts from 1): i. Build the tree using the above-mentioned numbers where the internal nodes represent the sum of values within a given range. ii. Increment all values within the range (4,8) by 5 . iii. Increment all values within the range (1,9) by 10 . iv. Show the summation of the range (2,4). v. Show the summation of the range (3,7). vi. Add 7 to the value at index-8
