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 {?
-1) t) { return true; } } } return false; }}2, with a map implementation, similar to the principle of bucket sequencing, first turn the data into positive numbers, and the use of long (otherwise error, such as 2 and 2 divided by 3 equals 0, but 4 is greater than 3), while the bucket (t) = t + 1 (t = = 0 of the case to be discharged) Public classSolution { Public BooleanContainsnearbyalmostduplicate (int[] Nums,intKintt) {if(K ){ return false

Swift is an interpreted language. Can it be so fast, or 210 times faster than the speed of some special functions? Should the four arithmetic operations not be improved so much? Swift is an interpreted language. Can it be so fast, or 210 times

This problem is caused by the choice of non-Intersecting intervals. It is important to model the actual problem as a basic problem. For example, both Room 3 and Room 4 should "add one, divide

Question: Give You n strings and find the longest common compound substring.
Analysis: It is similar to the longest common repeated substrings of two strings. It is also used to synthesize all strings
Swift is an interpreted language, can it really do that fast, or 210 times times just a special feature on the speed of comparison, arithmetic should not be promoted so much?
Reply content:Contrary to the intuition of the questioner, arithmetic is

Android ANR solution case (internal information)
When ANR occurs, you first need to view the log information and trace file (the system will generate a trace file in the/data/anr/directory) to analyze the cause of ANR. The following analysis does not solve all the ANR problems encountered, but the ANR problems caused by the program itself can basically find the cause.
