Java Loops | HackerRank solutions -codewithyasar

  Objective In this challenge, we're going to use loops to help us do some simple math. Task Given an integer,  , print its first   multiples. Each multiple   (where  ) should be printed on a new line in the form:  N x i = result . Input Format A single integer,  . Constraints Output Format Print   lines of output; each line   (where  ) contains the   of   in the form: N x i = result . Sample Input 2 Sample Output 2 x 1 = 2 2 x 2 = 4 2 x 3 = 6 2 x 4 = 8 2 x 5 = 10 2 x 6 = 12 2 x 7 = 14 2 x 8 = 16 2 x 9 = 18 2 x 10 = 20 Explanation:           Here, we just need to use for loops to achieve the result Solution : import java.io.* ; import java.math.* ; import java.security.* ; import java.text.* ; import java.util.* ; import java.util.concurrent.* ; import java.util.regex.* ; public class Solution { public static void main ( String [] args ) throws IOException { BufferedReader bufferedReader = new BufferedReader ( new InputStreamReader ( Syste

GCD Matrix


GCD Matrix

In mathematics, the greatest common divisor (gcd) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4.

You are given a 2D array, find the GCD of the elements in the diagonals of the matrix.


Input Format : The first line of input has one single integer N The next N lines will have N spaced integer inputs

Input Constraints : 1<=N<=100 1<=a[i]<=100

Output Format : One single integer output denoting the GCD of the diagonal elements

Sample Input :2 1 2 3 4

Sample Output :

1

Explanation:

We need to find the gcd among the diagonal of the matrix

Super ASCII String Checker | CodeVita | PYTHON CODE

Problem: In the Byteland country a string "S" is said to super ascii string if and only if count of each character in the string is equal to its ascii value. In the Byteland country ascii code of 'a' is 1, 'b' is 2 ...'z' is 26. Your task is to find out whether the given string is a super ascii string or not. Input Format: First line contains number of test cases T, followed by T lines, each containing a string "S". Output Format: For each test case print "Yes" if the String "S" is super ascii, else print "No" Constraints: 1<=T<=100 1<=|S|<=400, S will contains only lower case alphabets ('a'-'z'). Explanation: For eg1 - String "bba" is super ascii string Explanation:- .String "bba" The count of character 'b' is 2. Ascii value of 'b' is also 2. The count of character 'a' is 1. Ascii value of 'a' is also 1. Hence string "bba"

Lexi String | codevita |Python Solution

Lexi String Little Jill jumbled up the order of the letters in our dictionary. Now, Jack uses this list to find the smallest lexicographical string that can be made out of this new order. Can you help him? You are given a string P that denotes the new order of letters in the English dictionary. You need to print the smallest lexicographic string made from the given string S. Constraints: 1 <= T <= 1000 Length (P) = 261 <= length (S) <= 100 All characters in the string S, P are in lowercase Input Format The first line contains number of test cases T The second line has the string P The third line has the string S Output Print a single string in a new line for every test case giving the result Test Case Example 1 Input 2 polikujmnhytgbvfredcxswqaz abcd qwryupcsfoghjkldezxvbintma ativedoc Output bdca codevita Explanation: The transformed smallest lexicographical strings are in order they would be if order of letters are changed to string P
