Consider the following two threads, they will run concurrently in a shared memory (all variables are shared between the two threads): Thread A Thread B for i = 1 to 5 do for j = 1 to 5 do x = x + 1; x = x + 1; Assuming a single-processor system, that load and store are atomic, that x is initialized to 0, and that x must be loaded into a register before being incremented (and stored back to memory afterwards). Question 1: Briefly explain why xs10 when both threads have completed. Question 2: Briefly explain why x#1 when both threads have completed
