We would like to use for loop the show the following pattern.
Pattern://from w w w . j a va 2 s . c o m 1 1 2 1 1 2 4 2 1 1 2 4 8 4 2 1 1 2 4 8 16 8 4 2 1 1 2 4 8 16 32 16 8 4 2 1 1 2 4 8 16 32 64 32 16 8 4 2 1 1 2 4 8 16 32 64 128 64 32 16 8 4 2 1
public class Main { public static void main(String[] args) { int startRight = 0, // Initialize decending numbers endSpace = 7; // Initialize number of white space in row // Display number of rows and numbers in each row //your code here } }
public class Main { public static void main(String[] args) { int startRight = 0, // Initialize decending numbers endSpace = 7; // Initialize number of white space in row // Display number of rows and numbers in each row for (int row = 1; row <= 128; row += row) { // Display white space for (int startSpace = 0; startSpace < endSpace; startSpace++) { System.out.print(" "); } // Display acending numbers for (int l = 1; l <= row; l += l) { System.out.printf("%4d", (l)); } // Display decending numbers for (int r = startRight; r > 0 ; r /= 2 ) { System.out.printf("%4d", (r)); } System.out.println(); // End line endSpace--; // Decrement endSpace startRight = row; // Assign row to startRight } } }
