Question

Using stacks, how to obtain the binary representation of the number?

Options:

A . public void convertBinary(int num){ Stack stack = new Stack(); while (num != 0) { int digit = num / 2;stack.push(digit); } System.out.print("\nBinary representation is:"); while (!(stack.isEmpty() )) { System.out.print(stack.pop()); } }

B . public void convertBinary(int num){ Stack stack = new Stack(); while (num != 0) { int digit = num % 2; stack.push(digit); } System.out.print("\nBinary representation is:"); while (!(stack.isEmpty() )) { System.out.print(stack.pop()); } }

C . public void convertBinary(int num){ Stack stack = new Stack(); while (num != 0) { int digit = num % 2; stack.push(digit); num = num / 2; } System.out.print("\nBinary representation is:"); while (!(stack.isEmpty() )) { System.out.print(stack.pop()); } }

D . None of the above

Answer: Option C

Here instead of adding the digits to an array, you push it into a stack and while printing, pop it from the stack.
