Suppose you are given the following code:
class FooBar { public void foo() { for (int i = 0; i < n; i++) { print("foo"); } } public void bar() { for (int i = 0; i < n; i++) { print("bar"); } } }
The same instance of `FooBar` will be passed to two different threads:
* thread `A` will call `foo()`, while
* thread `B` will call `bar()`.
Modify the given program to output `"foobar"` `n` times.
**Example 1:**
**Input:** n = 1
**Output:** "foobar"
**Explanation:** There are two threads being fired asynchronously. One of them calls foo(), while the other calls bar(). "foobar" is being output 1 time.
**Example 2:**
**Input:** n = 2
**Output:** "foobarfoobar"
**Explanation:** "foobar" is being output 2 times.
**Constraints:**
* `1 <= n <= 1000`
