Range Sum Queries
You are given an integer array `nums` and a list of queries. Each query consists of two integers `L` and `R`, and you need to find the sum of the elements in the range from index `L` to `R` (inclusive). Write a program that takes the array and the queries, and prints the sum for each query.
Input format:
- The first line contains an integer `n`, the number of elements in the array.
- The second line contains `n` space-separated integers representing the elements of the array `nums`.
- The third line contains the integer `q`, the number of queries.
- The next `q` lines contain two integers `L` and `R` (0-indexed).
Output format:
- Output `q` lines, each containing the sum for the corresponding query.
Example:
Input:
5
2 4 6 8 10
2
0 2
1 4
Output:
12
38
