Sum of Diagonal Elements of Matrix

Sum of Diagonal Elements of Matrix:


Program:

import java.util.Scanner;

public class DiagonalAndOffDiagonalSum {

public static void main(String[] args) {

int r, c;

Scanner s = new Scanner(System.in);

r = s.nextInt();

c = s.nextInt();

if(r!=c) {

System.out.println("Please enter dimensions of square matrix");

}

int[][] matrix = new int[r][c];

for(int i = 0; i<r; i++) {

for(int j = 0; j<c;j++) {

matrix[i][j] = s.nextInt();

}

}

int dig1 = 0, dig2 = 0;

for(int i = 0 ; i < r; i++) {

dig1+=matrix[i][i];

dig2+=matrix[i][r-1-i];

}

System.out.println("The Sum of diagonal1 is:" + " " + dig1);

System.out.println("The Sum of diagonal2 is:" + " " + dig2);

}

}


Output:

Valid Username Regular Expression

Valid Username Regular Expression: Problem Description: You are updating the username policy on your company's internal networking platform. According to the policy, a username is considered valid if all the following constraints are satisfied: The username consists of 8 to 30 characters inclusive. If the username consists of less than  or greater than 8 characters, then it is an invalid username. The username can only contain alphanumeric characters and underscores (_). Alphanumeric characters describe the character set consisting of lowercase characters[a-z] , uppercase characters[A-Z] , and digits[0-9]. The first character of the username must be an alphabetic character, i.e., either lowercase character [a-z] or uppercase character [A-Z]. Update the value of regularExpression field in the UsernameValidator class so that the regular expression only matches with valid usernames. Input Format The first line of input contains an integer , describing the total number of usernames. Ea...
