1115 - Print FooBar Alternately.
Medium
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:
A will call foo(), whileB 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.
