Write a Java program that reads an integer n from the keyboard and loops until $13<=$ n $<=13$ is

successfully entered $($In other words, your loop must break if n is equal to or in between $-13$ and $13).$

A do$-$while loop is advised.

$2.$ Write a Java program that reads an integer n from the keyboard and prints the corresponding

value n$!.$ You must verify that the input integer satisfies the constraint $0<=$ n $<=13$; keep looping

until the constraint is satisfied. $($In other words, your loop must break if n is not in the given range

$0<=$ n $<=13)$

$3.$ Write a Java program to print the pattern consistent with the progression:

x xx xxx xxxx xxxxx

The program should prompt the user for the desired length of the pattern; the input integer

indicates the last block of asterisks. For simplicity, interpret a negative value positively; that is$,$ use

absolute value.
