Ace Test Series: Operating System - Semaphore
It says as follows: Pseudocode Integer X = 0 , Y = 23 ; Semaphore mx = 1 , my = Null ; Codebegin Begin P(mx); x= x+1; V(my); End Begin P(my); x= y+1; V(mx); End Question: Possible final values of X?? I tried to find the values and i concluded that 1 and 24 could be the final values but solution says only 24 :( Any idea??
