what's the problem ?
![```
// This program counts down to 0 from
// the number the user enters
public static void main(String[] args) {
int num = readInt("Enter number: ");
for(int i = num; i >= 0; i--)
System.out.println(i);
}
// This program prints "hello" as many
// times as the user enters
public static void main(String[] args) {
var num = readInt("Enter number: ");
for(int i = 0; i < num; i++) {
System.out.println("hello");
}
}
```
### Explanation
#### First Program:
- **Functionality**: This code snippet is designed to count down from a user-provided number to 0.
- **Variable**: `num` stores the user input.
- **Loop**: A `for` loop iterates, starting from `num` and decrements until it reaches 0, printing each number.
#### Second Program:
- **Functionality**: This snippet prints the word "hello" a number of times as specified by the user.
- **Variable**: `num` stores the user input.
- **Loop**: A `for` loop runs from 0 to one less than `num`, printing "hello" during each iteration.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F910c6dd5-c63e-4d7f-aae4-97889656c3db%2F6b0cc24d-876e-4af0-aeaf-e76af8c673e3%2Fdstlwjp_processed.jpeg&w=3840&q=75)
