Topic: Given an array of integers, find if the array contains any duplicates. Your function should return TRUE if any value appears at least twice in the array, and it should return FALSE if every ele ment is distinct. Effect: An array of type int is given to determine if the array contains duplicate numbers. If any of the values occur at least two times in the function, your array sh

The original title link is here: https://leetcode.com/problems/contains-duplicate-iii/With the help of TreeSet's subset function, see if there is a number in the range [Nums[i]-t, nums[i]+t+1].maintains a window of length k, which takes the front element out of the window when it exceeds this length.If within the window length range, add nums[i] into the window.Note: If i>=k, take this nums[i-k] out of the window because I is starting from 0 and K is

As described in the previous section: the EQ (index) selector, when looking for an element by index, sometimes we might want to find one or more elements according to the text content , so :contains(text) it is more convenient to use selectors, and its function is to choose to include Specifies the entire element of the string, which is typically used in conjunction with other elements to get all the element objects containing the contents of the "tex

This problem gets much trickier than Contains Duplicate and Contains Duplicate ii.The basic idea was to maintain a window of K numbers. For each new number, if there exists a number in the window with difference not larger than K, then return TR UE. When we check every number and has not returned true, return false. Remember that we need to update the Windows (erase the earliest added element) after it had
