What is a spiral Order matrix?

The Spiral Matrix problem takes a 2-Dimensional array of N-rows and M-columns as an input, and prints the elements of this matrix in spiral order. The spiral begins at the top left corner of the input matrix, and prints the elements it encounters, while looping towards the center of this matrix, in a clockwise manner.

How do you print a matrix in a clockwise spiral?

Draw the path that the spiral makes….Algorithm:

1. Create and initialize variables k – starting row index, m – ending row index, l – starting column index, n – ending column index.
2. Run a loop until all the squares of loops are printed.
3. In each outer loop traversal print the elements of a square in a clockwise manner.

How do you make a spiral of numbers spiral matrix in Java?

Implementation

1. import java. io. *;
2. class MAIN {
3. public static void spiralMatrixPrint(int[][] arr) {
4. ​
5. int rows = arr. length;
6. int cols = arr[0]. length;
7. // Defining the boundaries of the matrix.
8. int top = 0, bottom = rows – 1, left = 0, right = cols – 1;

How do I print a element in spiral order?

In order to print a matrix in spiral form, you need to follow the below approach.

1. Left to right (first row)
2. Top to bottom (Last column)
3. Right to left (last row)
4. Bottom to top (First column)

How do you print a matrix array?

public class Print2DArray { public static void main(String[] args) { final int[][] matrix = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; for (int i = 0; i < matrix. length; i++) { //this equals to the row in our matrix. for (int j = 0; j < matrix[i]. length; j++) { //this equals to the column in each row.

What is spiral matrix in Java?

The Spiral Matrix problem takes as an input a 2-Dimensional array of N rows and M columns and prints the elements of this matrix in spiral order. The spiral begins at the top left corner of the input matrix and prints the elements it encounters while looping towards the center of this matrix in a clockwise manner.

How do you loop through a multidimensional array in PHP?

Looping through multidimensional arrays Just as with regular, single-dimensional arrays, you can use foreach to loop through multidimensional arrays. To do this, you need to create nested foreach loops — that is, one loop inside another: The outer loop reads each element in the top-level array.

How do you do two for loops in Java?

Java Nested for Loop

1. public class NestedForExample {
2. public static void main(String[] args) {
3. //loop of i.
4. for(int i=1;i<=3;i++){
5. //loop of j.
6. for(int j=1;j<=3;j++){
7. System.out.println(i+” “+j);
8. }//end of i.
