You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 456. 132 Pattern.go
    path of file: ./repos/LeetCode-Go/leetcode/0456.132-Pattern
    
    the code of the file until where you have to start completion: package leetcode

import (
	"math"
)

// 解法一 单调栈
func find132pattern(nums []int) bool {
	if len(nums) < 3 {
		return false
	}
	num3
    
func find132pattern1(nums []int) bool {
	if len(nums) < 3 {
		return false
	}
	for j := 0; j < len(nums); j++ {
		stack := []int{}
		for i := j; i < len(nums); i++ {
			if len(stack) == 0 || (len(stack) > 0 && nums[i] > nums[stack[len(stack)-1]]) {
				stack = append(stack, i)
			} else if nums[i] < nums[stack[len(stack)-1]] {
				index := len(stack) - 1
				for ; index >= 0; index-- {
					if nums[stack[index]] < nums[i] {
						return true
					}
				}
			}
		}
	}
	return false
