(adsbygoogle = window.adsbygoogle || []).push({}); Solution of Program 1 of ISC 2019 Computer Science Paper 2 (Practical) Exam. In this section we will be providing you with the Sample/Guess papers of ICSE (Computer Applications) and ISC (Computer Science) which can be easily downloaded. Given a 2D array, print it in spiral form. Write a Program in Java to fill a square matrix of size ‘n*n” in a circular fashion (clockwise) with natural numbers from 1 to n*n, taking ‘n’ as input. it will be R2-1. 2 Comments. My solutions.

Write a program in Java to create a two-dimensional array of size [n × n]. import java.util.Scanner; public class JavaSpiralMatrix { public static void main(String args[]) … The filling up of the matrix in circular fashion will consist of 4 different steps which will continue till the matrix is filled completely. Print Matrix in Spiral order OR Given m*n matrix, print all elements of the matrix in spiral order. For example: if n = 5, then n*n = 25, hence the array will be filled as given below. Print elements of the matrix in spiral order in Recursive way. Spiral Matrix. Printing a matrix in spiral order can be better understood by the following image. *; To start, we’ll need to write a function that accepts an argument of an integer. It was so helpful and your instructions we amazing. util. 2. Java program to find the future date. Is it acceptable in an ISC practical examination? To summarize, we construct a list with n*n elements by following some simple rules, then take its cumulative sum, and finally its inverse permutation (or grade in J parlance). Java Program to Print Matrix in Spiral order. For example: if n = 4, then n*n = 16, hence the array will be filled as given below. Java program to print the following spiral pattern on the console Algorithm: STEP 1: START STEP 2: SET i=1,j=1,k=1,l=1,direction=1 STEP 3: SET matrix[10][10] STEP 4: REPEAT STEP 5 to 9 UNTIL i is less than 10 STEP 5: SET j=0 STEP 6: REPEAT STEP 7 and 8 UNTIL j is less than 10 STEP 7: SET matrix[i][j]=0 STEP 8: SET j=j+1 STEP 9: SET i=i+1 // steps for printing the matrix String/Array (41) Two Pointer (36) Math (24) DP (20) Subset (18) Linked List (17) DFS (16) HashTable (12) D&C (10) Binary Tree (9) Bit Manipulate (9) Greedy (7) Matrix (7) Database (6) Design (5) BFS (3) BST (2) Binary Search (2) Integer Overflow (2) Stack (2) Topological Sort (2) Airstream (1) Graph (1) Heap (1) Morris Traversal (1) Wednesday, March 18, 2015. ↓ 4 → 5 6 ↑ ↓ 7 ← 8 ← 9. Java program for spiral matrix Outer spiral matrix – arrows are from boundary to core element. Spiral Matrix. How to print elements of Matrix in Spiral Format. thank you so much sir.. its very useful…. import java.io. Better to do using functions, implementing OOP. sir..thank you so much..i never understood this program anywhere in school or coaching..bt you have explained it beautifully..thnk u so much We have to print the matrix elements in a spiral way. For example, given the following matrix: [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ] You should return [1,2,3,6,9,8,7,4,5]. Your email address will not be published. Sort the array elements in ascending order September 26, 2018; Shuffle the matrix(2D)(1st row becomes the last, 2nd row becomes the 1st & so on..) — by object September 26, 2018; Clockwise Spiral matrix/circular matrix in java September 22, 2018; Random numbers September 1, 2018; oops concept August 31, 2018; Functions/Methods July 14, 2018 Print Matrix in Spiral order using Recursion. it will be C1+1. Note: This program is also known as Spiral Matrix, See: Java program to print a variation of Circular (Spiral) Matrix, We will take a variable ‘k’ which will begin with 1 and will do the work of filling. Given two values m and n, fill a matrix of size ‘m*n’ in spiral (or circular) fashion (clockwise) with natural numbers from 1 to m*n. Examples: Input : m = 4, n = 4 Output : 1 2 3 4 12 13 14 5 11 16 15 6 10 9 8 7 Input : m = 3, n = 4 Output : 1 2 3 4 10 11 12 5 9 8 7 6 class spiral {public static void main (String args []) Scanner obj = new Scanner (System.
