Contiguous Subarray Sum

Given an array of integers, you need to find a contiguous subarray whose sum equals a target value. Print the starting and ending indices of the subarray (zero-based, inclusive); if no such subarray exists, print -1. The input consists of two lines; the first line contains an integer `target`, and the second line contains the integers of the array. Example: Input: 5 1 2 3 4 5 Output: 0 1
