Topic: Given n strings, the oldest string that appears at least two times for each string.How to solve the problem: at least two occurrences of each string and non-overlapping eldest-son string: Two-enumeration length after each string in the same group to keep a minimum position and a maximum position, and finally see if each string in the same group has at least two suffixes, and the suffix of the coordinate is greater than the length of the enumeration.POJ problem Set (classical)

Given an array of integers, find out whether there is II distinct indices i and J in the array such th At the difference between nums[i] and Nums[j] are at most T and the difference between I and J I S at the most K.Thought for reference: maintain a window of length k, each time checking whether the new value is less than or equal to the value of all values in the original window. If the two for loop will time out O (NK). You can quickly search by using the subset function of TreeSet (backed by

Leetcode 220 Contains Duplicate III1. Problem Description Given an integer array nums [], check whether two subscripts I and j exist. | Numsi? Numsj | ≤ t And | I? J | ≤ k . 2. methods and ideas The general idea is: "Sliding Window" + unordered_map.The reasoning process is as follows:　　 | Numsi? Numsj | ≤ t? | Numsi/t? Numsj/t | ≤ 1 ;From above, we can launch: |? Numsi/t ??? Numsj/t? | ≤ 1 It is equivalent: ? Numsi/t? ε {?

to know where to go, there are several on the line in use? Fair bet the fruit powder. This time, I really despise. Swift compiles the machine code, and Python (which should be CPython) compiles the bytecode that the Python virtual machine runs. So in the vast majority of scenarios, there is certainly a huge difference in operational efficiency. But I think 210 times times this value is the conclusion in a particular scene that can appear swift quickly. In fact, the comparability of swift and

Since when the new number comes in, we need to compare it to the size of other numbers in the window, we can use BS
