Answer:
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(" ");
}
}
}
Step-by-step 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.
