Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.

The sensor of a mouse connected to the computer or the touch pad being touched and swiped around on
Answer:
name = input("Enter name: ")
droids = int(input("How many droids you want to meet? "))
wookies = int(input("How many Wookies you want to meet? "))
print(name + " wants to meet " + str(droids) + " droids, and " + str(wookies) + " Wookies")
Explanation:
*The code is in Python.
Ask the user to enter the name, number of the droids and number of the Wookies
Print the name, number of the droids, and number of the Wookies
Note that while getting the input for the droids and wookies, you need to typecast the input the int (Since the values are int). Also, to print these variables, you need to typecast them as string in that format.
