You are given a string num representing a large integer. An integer is good if it meets the following conditions:It is a substring of num with length 3.It consists of only one unique digit.Return the

On a 2D plane, there are n points with integer coordinates points[i] = [xi, yi]. Return the minimum time in seconds to visit all the points in the order given by points. You can move according to

You are given an array of strings words and a string chars. A string is good if it can be formed by characters from chars (each character can only be used once). Return the sum of lengths of all good

You are given a 0-indexed integer array arr, and an m x n integer matrix mat. arr and mat both contain all the integers in the range [1, m * n]. Go through each index i in arr starting from index 0 an

You are given a binary matrix matrix of size m x n, and you are allowed to rearrange the columns of the matrix in any order. Return the area of the largest submatrix within matrix where every element

You are given an integer array nums sorted in non-decreasing order. Build and return an integer array result with the same length as nums such that result[i] is equal to the summation of absolute diff

Given a 2D integer array nums, return all elements of nums in diagonal order as shown in the below images. Example 1:Input: nums = [[1,2,3],[4,5,6],[7,8,9]]Output: [1,4,2,7,5,3,8,6,9] Example 2:I

A sequence of numbers is called arithmetic if it consists of at least two elements, and the difference between every two consecutive elements is the same. More formally, a sequence s is arithmetic if

Given a 0-indexed integer array nums of size n and two integers lower and upper, return the number of fair pairs. A pair (i, j) is fair if:0 <= i < j < n, andlower <= nums[i] + n

Given a 0-indexed integer array nums of length n and an integer target, return the number of pairs (i, j) where 0 <= i < j < n and nums[i] + nums[j] < target. Example 1:Input: nums &#
