We have n jobs, where every job is scheduled to be done from startTime[i] to endTime[i], obtaining a profit of profit[i].You're given the startTime, endTime and profit arrays, return the maximum profit you can take such that there are no two jobs in the subset with overlapping time…

Given the head of a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x.You should preserve the original relative order of the nodes in each of the two partitions.Example 1:

Your friend is typing his name into a keyboard. Sometimes, when typing a character c, the key might get long pressed, and the character will be typed 1 or more times.You examine the typed characters of the keyboard. Return True if it is possible that it was your friends…

There’s a lot of different, good articles about REST on the internet. However, the most accurate understanding you get when you refer to the initial source (a famous Roy Fieldings’ dissertation about architecture styles, and its 5th chapter). Nevertheless, let’s look at some important points shortly.

The string "PAYPALISHIRING" is written in a zigzag pattern on a given number of rows like this: (you may want to display this pattern in a fixed font for better legibility)P A H N A P L S I I G Y I RAnd then read line by…

Given an integer n, return all the strobogrammatic numbers that are of length n. You may return the answer in any order.A strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Example 1:Input: n = 2 Output: ["11","69","88","96"] Example 2: Input: n = 1 Output: ["0","1","8"] Constraints: 1 <= n <= 14

The idea is simple: we begin from the middle of the word and recursively create all possible strings of length from 1 (or 0, depending on even n or odd) to n: This is the example for n odd and 0. Besides 0, we need to construct the same trees with 8 and 1 as root. If n is even, root will be empty

Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements.Note that you must do this in-place without making a copy of the array. Example 1:Input: nums = [0,1,0,3,12] Output: [1,3,12,0,0] Example 2:Input: nums = [0] Output…
