2395 - Find Subarrays With Equal Sum\.

Easy

Given a 0-indexed integer array nums, determine whether there exist two subarrays of length 2 with equal sum. Note that the two subarrays must begin at different indices.

Return true if these subarrays exist, and false otherwise.

A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:

Input: nums = 4,2,4

Output: true

Explanation: The subarrays with elements 4,2 and 2,4 have the same sum of 6.

Example 2:

Input: nums = 1,2,3,4,5

Output: false

Explanation: No two subarrays of size 2 have the same sum.

Example 3:

Input: nums = 0,0,0

Output: true

Explanation: The subarrays [nums0,nums1] and [nums1,nums2] have the same sum of 0.

Note that even though the subarrays have the same content, the two subarrays are considered different because they are in different positions in the original array.

Constraints:

• 2 <= nums.length <= 1000

• <code>-10⁹<= numsi<= 10⁹</code>
