Task 1: Range Sum

Submitted by: [50]Mohammad Sajid Anwar
     __________________________________________________________________

   You are given a list integers and pair of indices..

   Write a script to return the sum of integers between the given indices
   (inclusive).

Example 1

Input: @ints = (-2, 0, 3, -5, 2, -1), $x = 0, $y = 2
Output: 1

Elements between indices (0, 2) => (-2, 0, 3)
Range Sum: (-2) + 0 + 3 => 1

Example 2

Input: @ints = (1, -2, 3, -4, 5), $x = 1, $y = 3
Output: -3

Elements between indices (1, 3) => (-2, 3, -4)
Range Sum: (-2) + 3 + (-4) => -3

Example 3

Input: @ints = (1, 0, 2, -1, 3), $x = 3, $y = 4
Output: 2

Elements between indices (3, 4) => (-1, 3)
Range Sum: (-1) + 3 => 2

Example 4

Input: @ints = (-5, 4, -3, 2, -1, 0), $x = 0, $y = 3
Output: -2

Elements between indices (0, 3) => (-5, 4, -3, 2)
Range Sum: (-5) + 4 + (-3) + 2 => -2

Example 5

Input: @ints = (-1, 0, 2, -3, -2, 1), $x = 0, $y = 2
Output: 1

Elements between indices (0, 2) => (-1, 0, 2)
Range Sum: (-1) + 0 + 2 => 1
