Given a sequence of n integers a1, a2, ..., an, a 132 pattern is a subsequence ai, aj, ak such that i < j < k and ai < ak < aj. Design an algorithm that takes a list of n numbers as input and checks whether there is a 132 pattern in the list.…
Given a pattern and a string str, find if str follows the same pattern. Examples: pattern = "abba", str = "dog cat cat dog" should return true. pattern = "abba", str = "dog cat cat fish" should return false. pattern…
456. 132 Pattern Given an array of integers a1, a2, a3-an, judge if there exists the 132 pattern. 132 pattern is ai < ak < aj, in which i < j < k. Solution: refer: https://discuss.leetcode.com/topic/67881/single-pass-c-o-n-space-and-time-solut…

1. 1-bit and 2-bit Characters We have two special characters. The first character can be represented by one bit 0. The second character can be represented by two bits (10 or 11). Now given a string represented by several bits. Return whether the last…
对一个三个元素以上的数组,如果存在1-3-2模式的组合,则返回true. 1-3-2模式就是值的排序是i<k<j但是下标排序是i<j<k. 解法一: 硬解,利用一个变量存储是否找到了较大值和较小值,因为是1-3-2,所以从后往前遍历才能找到较当前值更大和更小的值. Runtime: 648 ms, faster than 12.76% of C++ online submissions for 132 Pattern. class Solution { public: bool f…
