Explanation of Solution

Code walkthrough:

The below is the code walkthrough of the selection sort algorithm with the array of different length:

Array length being 0 or 1:

  • When the value of “i” is equal to “0” then “i<a.length-1” is not true.
  • The “for” loop that is present in the sort method will never execute and the array will remain unchanged.

Array length being 2:

  • The “for” loop that is present in the sort will execute once.
  • When the value of “i=0” then “minimumPosition(a,0)” gets called.
  • The “for” loop that is present gets executed from “=i” that is from 1 till less than 2, that is the loop will be executed once.
  • The value of “minPos” is initially set to “0”.
  • If the value of “a[1] is less than a[0]” then the value of “minPos” will be set to “1”.
  • Finally when the method returns the values, two values will be swapped and that will make the array to be sorted...

Question D.4: FIFO Page Replacement Consider the following page reference string: e, c, b, e, a, g, d, c, e, g, d, a Considering 4 frames, fill in the following table and then answer how many page faults would occur with the FIFO page replacement algorithm. RS: reference string; FO: frame 0, F1: frame 1, etc. Hint: all frames are initially empty, so your first unique pages will all cost one fault each. Time 1234567891011 12 RS e cb e agd ce g d a FO F1 F2 F3 Page fault? b) Total # page faults: c) Briefly (1-2 sentences) explain Belady's Anomaly that can occur in FIFO Page Replacement.
Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident process. How many bits are required for the pointer in the process table? Show all your steps.
