Question

Write Java program Lab42.java which takes as input two positive
integers m and n and computes their *least common multiple*
by calling method lcm(m,n), which in turn calls recursive method
gcd(m,n) computing the *greatest common divisor* of m and n.
Recall, that lcm(m,n) can be defined as quotient of m * n and
gcd(m,n).

Answer #1

C CODE PLZ! All instructions are in sections of code
#include <stdio.h>
/* TODO: Define 3 functions input, gcd and lcm in such a
way that the main function below compiles correctly and
has the correct behavior.
The input function prompts the user to enter a non-negative
integer. If the user enters a negative integer, the function prints
a "sorry" statement and prompts the user again. It keeps on
prompting until the user enters a non-negative number. The input
function...

Complete the program below. The program takes in two positive
integers, n and m, and should print out all the powers of n that
are less than or equal to m, on seperate lines. Assume both n and m
are positive with n less than or equal to m.
For example, if the input values are n = 2 and m = 40 the output
should be:
2
4
8
16
32
Starter code:
import java.util.Scanner;
public class Powers {...

Java Program
Write a method called “fillMatrix” that takes two integers rows
and cols and returns a 2D array of integers of size rows x cols
where the value of element [row][col] is row + col. Write a short
program to test your method.

Write Java program Lab51.java which takes in a string from the
user, converts it to an array of characters (char[] word) and calls
the method:
public static int countVowels(char[])
which returns the number of vowels in word. (You have to write
countVowels(char[]) ).
