Given two binary strings a and b, return their sum as a binary string. Example 1: Input: a = "11", b = "1" Output: "100" Example 2: Input: a = "1010", b = "1011" Output: "10101" Constraints: 1 = 0 { switch { case carry == 1: if aa[alen] == "0" && bb[blen] == "0" { ans = append([]string{"1"}, ans...) carry = 0 alen-- blen-- } else if aa[alen] == "1" && bb[blen] == "0" || aa[alen] == "0" && bb[ble..

Given an integer numRows, return the first numRows of Pascal's triangle. In Pascal's triangle, each number is the sum of the two numbers directly above it as shown: Example 1: Input: numRows = 5 Output: [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]Example 2: Input: numRows = 1 Output: [[1]]Constraints: 1

Given an m x n matrix, return all elements of the matrix in spiral order. Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [1,2,3,6,9,8,7,4,5]Example 2: Input: matrix = [[1,2,3,4],[5,6,7,8],[9,10,11,12]] Output: [1,2,3,4,8,12,11,10,9,5,6,7]Constraints: m == matrix.length n == matrix[i].length 1 Left -> Up. Becuase for loop runs until end of restrict, if condition for break is needed...

Given an integer array nums sorted in non-decreasing order, return an array of the squares of each number sorted in non-decreasing order. Example 1: Input: nums = [-4,-1,0,3,10] Output: [0,1,9,16,100] Explanation: After squaring, the array becomes [16,1,0,9,100]. After sorting, it becomes [0,1,9,16,100].Example 2: Input: nums = [-7,-3,2,3,11] Output: [4,9,9,49,121]Constraints: 1 0 { return x } r..
