Both process arrive at the while loop at the same time

If both process arrive at while loop simultaneously then one while loop will definitely be false because turn value will be either i or j

isnt it???

---

process I()

{

   while(turn == j    &&  flag[j] ==true)

}

 

process J()

{

   while(turn == i    &&  flag[i] ==true)

}
