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...

In the previous lesson, we had a healthy dosage of practical Go programming. When we finished writing our chat client for the hydra spaceship. In this section we'll begin to explore reflection in the Go language. We are going to take a look at.. What is Refelction Refresher on interfaces First law of reflection Second law of reflection Third law of reflection http://blog.golang.org/laws-of-r..

통상적으로 변수 등이 String으로 사용된다면 큰 차이는 없음. 그러나 String이 아닌 형태가 서로 결합한다면 문제가 발생함. Code func main() { sstring := fmt.Sprint("Hello ", "World") nstring := "Hello World" fmt.Println(sstring) fmt.Println(nstring) }https://go.dev/play/p/WO415NpCkSl 문제는 String이 아닌 Integer 등이 혼합될 때이다. Code func main() { Sequence := 254 sstring := fmt.Sprintf("Sequence number %d is on hold", Sequence) fmt.Println(sstring) nstri..

You are given a large integer represented as an integer array digits, where each digits[i] is the ith digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. The large integer does not contain any leading 0&#39;s. Increment the large integer by one and return the resulting array of digits. Example 1: Input: digits = [1,2,3] Output: [1,2,4] ..

You are given an integer array nums where the largest integer is unique. Determine whether the largest element in the array is at least twice as much as every other number in the array. If it is, return the index of the largest element, or return -1 otherwise. Example 1: Input: nums = [3,6,1,0] Output: 1 Explanation: 6 is the largest integer. For every other number in the array x, 6 is at least ..

Given an array of integers nums, calculate the pivot index of this array. The pivot index is the index where the sum of all the numbers strictly to the left of the index is equal to the sum of all the numbers strictly to the index's right. If the index is on the left edge of the array, then the left sum is 0 because there are no elements to the left. This also applies to the right edge of the ar..
