This is my code.I can't seem to be able to get the desired output,which in turn does not allow me to finish my task.I want to print a pyramid/triangle using the standart input.From this input:
5
5
10 20
1 3 1
99 20 7 40
5 15 25 30 35
I need to get this output
5
10 20
1 3 1
99 20 7 40
5 15 25 30 35
My result is as follows:
5
10 10
20 20 20
1 1 1 1
3 3 3 3 3
You need 2 loops: one to input the numbers and one to print the pyramid.
public static void main (String[] args) throws java.lang.Exception
{
// Get number of rows
System.out.println("Enter number of rows: ");
Scanner sc = new Scanner(System.in);
int numRows = sc.nextInt();
// Get all the numbers
System.out.println("Enter numbers:");
int numNumbers = numRows * (numRows + 1) / 2;
int [] numbers = new int[numNumbers];
for (int i = 0; i < numNumbers; i++) {
numbers[i] = sc.nextInt();
}
// Print the pyramid
for( ..... Leaving this blank as this looks like homework...) {
}
