System.out.println("Input an integer:");
int num = scan.nextInt();
String newTxt = "";
int w = 0;
for (int i = txt.length()-1; i >= 0; i--){
char c = txt.charAt(i);

Answer:
1111000
Explanation:
perform the following. write from right to left:
- is the number even? then write down a 0
- is the number odd? then write down a 1 and subtract 1
- divide by 2
- repeat until you reach 0.
So for 120:
120 is even, so write down a 0 and continue with 120/2=60
60 is even, so write down a 0 and continue with 60/2=30
30 is even, so write down a 0 and continue with 30/2=15
15 is odd, so write down a 1 and continue with 14/2=7
7 is odd, so write down a 1 and continue with 6/2=3
3 is odd, so write down a 1 and continue with 2/2=1
1 is odd, so write down a 1 and finish with 0
