Please explains why or why not? Thanks

(Q1) Given resource type X with two instances, resource type Y with a single instance, and three threads. As illustrated in there source allocation graph, Thread 0 owns resource type Y's instance and is waiting for resource type X Thread 1 owns one instance of resource type X. Thread 2 owns the other instance of resource type X and is waiting for resource type Y. Is there any deadlock? Why or why not? Thread 0 Waiting for Owned by Resource X Resource Y Thread 1 Owned by Owned by Waiting for Thread 2
