Suppose a system has not implemented any deadlock prevention and avoidances measurement. Therefore, it has to run the deadlock detection algorithm in case deadlock has occurred in a system. Following two strategies can be adopted to recover the system from a deadlock.

1. Abort the one or more processes to break the circular wait.
2. Preempt some resources from one or more processes to break the deadlock.

In your opinion, which option will be considered more suitable to recover the system from a deadlock? Write a concise and to the point answer with valid reasons.

Write a bash script to check whether the input number is EVEN, ODD or neither EVEN nor

LEARNING TASK#02: WHAT IS IT? BY SEQUENCING Directions: with the use of letters (a -f), arrange the PROGRAMMING PROCESS by reading the scenarios below. Write your answer on the space before the number.

1. In this phase, the programmer prepares a problem statement outlining the answers to the what is the job to be done?

2. In this phase, A plan of action is prepared describing the processing sequence of the operations and analyze what would be the best way to answer the problem.

3. In this phase, the programmer will write the source code and translate it to program

4. In this phase, Programs are tested to locate and correct programming errors or bugs.

5. In this phase, all data pertaining to a program are collected, organized, and recorded.
