Writhe the pseudocode to solve the matrix problem.

$1.$ int data$[3][3]$ records a $3$ by $3$ matrix.

$2.$ You need to create three worker threads by call pthread$\_$create in the main function.

$3.$ The first$-$created worker thread calculates the sum in the first line of the matrix; the second$-$created worker thread calculates the sum in the second line of the matrix; and The third$-$created worker thread calculates the sum in the last line of the matrix.

$4.$ The main function receives the result of each line from a worker thread and prints total sum.

$5.$ Synchronize the worker thread and the main function.

In your pseudocode, you need to clearly specify the input arguments in pthread$\_$create. You also need to clearly indicate the sem$\_$init, sem$\_$wait and sem$\_$post if you use semaphore in your pseudocode.
