Write a java program that will print out the following pattern 1 12 123 1234 12345

public class Main {

public static void main (String[] args)

{

int n, m;

int k=5;

for (n=1; n<=k; n++)

{

for (m=1; m<=n; m++)

System. out. print (m);

System. out. print (" ");

}

}

}

Explanation:

The solution to this problem is the use of nested loops of an inner and outer loop to generate a half pyramid of numbers, but displayed on the same line so we have a sequence 1 12 123 1234 12345. The outer loop iterates for n=1 to n<=5 and the inner loop that has the print statement prints the integers from for m = 1 to m<=n.

Note that the value k = 5 is hard coded which in some sense is the number of rows, that is the length of iteration of the outer loop.
