Hello Amigos! I don't know why the code I wrote is not meeting the last two requirements. My code gives instructions to print 10 numbers on the same line with spaces for each loop before incrementing the count by 1. I don't know where I am going wrong. Please help! See code below. public class Solution { public static void main(String[] args) { int count=1; while (count<=10){ //evaluates condition System.out.print(1*count+""); // System.out.print(2*count+""); System.out.print(3*count+""); System.out.print(4*count+"");
