2 * [2875] Minimum Size Subarray in Infinite Array
3 *
4 * You are given a 0-indexed array nums and an integer target.
5 * A 0-indexed array infinite_nums is generated by infinitely appending the elements of nums to itself.
6 * Return the length of the shortest subarray of the array infinite_nums with a sum equal to target. If there is no such subarray return -1.
7 *  
8 * <strong class="example">Example 1:
9 * 
10 * Input: nums = [1,2,3], target = 5
11 * Output: 2
12 * Explanation: In this example infinite_nums = [1,2,3,1,2,3,1,2,...].
13 * The subarray in the range [1,2], has the sum equal to target = 5 and length = 2.
14 * It can be proven that 2 is the shortest length of a subarray with sum equal to target = 5.
15 * 
16 * <strong class="example">Example 2:
17 * 
18 * Input: nums = [1,1,1,2,3], target = 4
19 * Output: 2
20 * Explanation: In this example infinite_nums = [1,1,1,2,3,1,1,1,2,3,1,1,...].
21 * The subarray in the range [4,5], has the sum equal to target = 4 and length = 2.
22 * It can be proven that 2 is the shortest length of a subarray with sum equal to target = 4.
23 * 
24 * <strong class="example">Example 3:
25 * 
26 * Input: nums = [2,4,6,8], target = 3
27 * Output: -1
28 * Explanation: In this example infinite_nums = [2,4,6,8,2,4,6,8,...].
29 * It can be proven that there is no subarray with sum equal to target = 3.
30 * 
31 *  
32 * Constraints:
33 * 
34 * 	1 <= nums.length <= 10^5
35 * 	1 <= nums[i] <= 10^5
36 * 	1 <= target <= 10^9
37 *
