Prоgrаmming: Threаds Cоnsider the fоllowing pаrtially implemented program. This program is intended to add two vectors (globals A and B) and store the output (global result) for printing. Each thread should add between A and B at a specific index and store the output in result at that same index. Assume that the number of threads and the number of elements in the vectors will ways match. Your program must allow the number of threads to be defined with the THREADS macro. Implement the program.
