542. 01 Matrix Medium Given an m x n binary matrix mat, return the distance of the nearest 0 for each cell. The distance between two adjacent cells is 1. Example 1: Input: mat = [[0,0,0],[0,1,0],[0,0,0]] Output: [[0,0,0],[0,1,0],[0,0,0]] Example 2: Input: mat = [[0,0,0],[0,1,0],[1,1,1]] Output: [[0,0,0],[0,1,0],[1,2,1]] Constraints: m == mat.length n == mat[i].length 1

1162. As Far from Land as Possible Medium Given an n x n grid containing only values 0 and 1, where 0 represents water and 1 represents land, find a water cell such that its distance to the nearest land cell is maximized, and return the distance. If no land or water exists in the grid, return -1. The distance used in this problem is the Manhattan distance: the distance between two cells (x0, y0)..

2306. Naming a Company Hard You are given an array of strings ideas that represents a list of names to be used in the process of naming a company. The process of naming a company is as follows: Choose 2 distinct names from ideas, call them ideaA and ideaB. Swap the first letters of ideaA and ideaB with each other. If both of the new names are not found in the original ideas, then the name ideaA ..

904. Fruit Into Baskets Medium You are visiting a farm that has a single row of fruit trees arranged from left to right. The trees are represented by an integer array fruits where fruits[i] is the type of fruit the ith tree produces. You want to collect as much fruit as possible. However, the owner has some strict rules that you must follow: You only have two baskets, and each basket can only ho..

1091. Shortest Path in Binary Matrix Medium Given an n x n binary matrix grid, return the length of the shortest clear path in the matrix. If there is no clear path, return -1. A clear path in a binary matrix is a path from the top-left cell (i.e., (0, 0)) to the bottom-right cell (i.e., (n - 1, n - 1)) such that: All the visited cells of the path are 0. All the adjacent cells of the path are 8-..

2091. Removing Minimum and Maximum From Array Medium You are given a 0-indexed array of distinct integers nums. There is an element in nums that has the lowest value and an element that has the highest value. We call them the minimum and maximum respectively. Your goal is to remove both these elements from the array. A deletion is defined as either removing an element from the front of the array..
