Given an Integer number convert into Binary Number using arrays as a stack.
Example:
Input : 10 Output: 1010 Input : 16 Output: 10000
Approach:
- Divide the number by 2 and store the remainder of the number in the array.
- Divide the number by 2.
- Repeat the process until the number becomes zero.
- Print the array in reverse order.

Java
// Java Program to Convert a Decimal Number// to Binary Number using Arrays as StacksÂ
import java.util.*;public class DecimalToBinary {Â Â Â Â static int arr[] = new int[1000];Â
    // maintaining count variable    // as the top of the stack    static int count;Â
    // push at the count index and increment the count    public static void push(int n) {      arr[count++] = n;    }Â
    // pop all the elements starting    // from count-1 till 0    public static void pop()    {        for (int i = count - 1; i >= 0; i--) {            System.out.print(arr[i]);        }    }Â
    public static void main(String args[])    {        int num = 46;Â
        while (num > 0) {            int r = num % 2;            push(r);            num /= 2;        }Â
        System.out.print("Binary equivalent: ");Â
        pop();    }} |
Binary equivalent: 101110
Time complexity: O(logn) for given input number n
