Given an array of distinct integers arr, find all pairs of elements with the minimum absolute difference of any two elements. Return a list of pairs in ascending order(with respect to pairs), each pair [a, b] follows a, b are from arr a < b b – a equals to the minimum absolute difference of any two elements in arr Example 1: Input: arr = [4,2,1,3] … Read more Minimum Absolute Difference in Python
On a plane, there are n points with integer coordinates points[i] = [xi, yi]. Your task is to find the minimum time in seconds to visit all points. You can move according to the next rules: In one second always you can either move vertically, horizontally by one unit or diagonally (it means to move one unit vertically … Read more Minimum Time Visiting All Points in Python
You are given a map of a server center, represented as a m * n integer matrix grid, where 1 means that on that cell there is a server and 0 means that it is no server. Two servers are said to communicate if they are on the same row or on the same column. Return the number … Read more Count Servers that Communicate in Python
Given an array of strings products and a string searchWord. We want to design a system that suggests at most three product names from products after each character of searchWord is typed. Suggested products should have common prefix with the searchWord. If there are more than three products with a common prefix return the three lexicographically minimums products. Return list of lists of the suggested products after each … Read more Search Suggestions System in Python
Tic-tac-toe is played by two players A and B on a 3 x 3 grid. Here are the rules of Tic-Tac-Toe: Players take turns placing characters into empty squares (” “). The first player A always places “X” characters, while the second player B always places “O” characters. “X” and “O” characters are always placed into empty squares, never on filled ones. The game ends when there are 3 … Read more Find Winner on a Tic Tac Toe Game in Python
Given two integers tomatoSlices and cheeseSlices. The ingredients of different burgers are as follows: Jumbo Burger: 4 tomato slices and 1 cheese slice. Small Burger: 2 Tomato slices and 1 cheese slice. Return [total_jumbo, total_small] so that the number of remaining tomatoSlices equal to 0 and the number of remaining cheeseSlices equal to 0. If it is not possible … Read more Number of Burgers with No Waste of Ingredients in Python

Problem: There are n people whose IDs go from 0 to n – 1 and each person belongs exactly to one group. Given the array groupSizes of length n telling the group size each person belongs to, return the groups there are and the people’s IDs each group includes. You can return any solution in any order and … Read more Group the People Given the Group Size They Belong To in Python
Problem: Given an array of integers nums and an integer threshold, we will choose a positive integer divisor and divide all the array by it and sum the result of the division. Find the smallest divisor such that the result mentioned above is less than or equal to threshold. Each result of division is rounded to the nearest integer greater than … Read more Find the Smallest Divisor Given a Threshold in Python
Problem: An integer has sequential digits if and only if each digit in the number is one more than the previous digit. Return a sorted list of all the integers in the range [low, high] inclusive that have sequential digits. Example: Constraints: Solution:
