Solution: 132 Pattern

Problem Statement

Given an array nums, containing N integers.

A 132 pattern consists of three numbers, say x, y, and z, where x < z and z < y. This is often referred to as a '132' pattern because if we represent x, y, and z as 1, 3, and 2, respectively, it mimics the positional pattern in '132'.

Return true if such a pattern exists within any sequence of given numbers nums. Otherwise, return false.

Examples

  1. Example 1:
    • Input: nums = [3, 5, 0, 3, 4]
    • Expected Output: True
