this is a C program, please note the question says "You $*$have$*$ to implement condition variable to obtain this output". Not using Semaphores.

Assume you have two threads; ThreadA and ThreadB. ThreadA prints "HELLO"

ten times and ThreadB prints "WORLD" ten times.

Write a $C$ code to create these two threads such that the output of your code must be

as follows:

You have to implement condition variable to obtain this output. It's your choice to

select an appropriate predicate variable. You can follow this hint.

Hint:

Declare a variable named turn of type character. Initially this variable has the value $\text{'}$A$\text{'}.$

Then, ThreadA prints "HELLO" only if the content of the variable turn is $\text{'}$A$\text{'}.$ Similarly,

ThreadB prints "WORLD" only if the content of the variable turn is $\text{'}$B$\text{'}.$

Use only one condition varaible.
