Question 1178 – Nielit Scientist-B CS 22-07-2017

A system has n resources R₀,..,R_n-1 and k processes P₀,..P_k-1. The implementation of the resources request logic of each process P
i is a follows:
if(i%2==0)
{
if(i<n) request R_i
if(i+2 <n) request R_i+2
}
else
{
if(i<n) request R_n-i
if(i+2 < n) request R_n-i-2
}
In which one of the following situations is a deadlock possible?

Correct Answer: B
