Write a program that uses two pipes to enable bidirectional communication between a parent and child process. The parent process should loop reading a block of text from standard input and use one of the pipes to send the text to the child, which converts it to uppercase and sends it back to the parent via the other pipe. The parent reads the data coming back from the child and echoes it on standard output before continuing around the loop once more.
