What is the value of the totalsString variable after the following code is executed? var totals = [141.95, 212.95, 411, 10.95];

Alex Ar [27]

<h2>Answer:</h2>

141.95|212.95|312.95|10.95|

<h2>Explanation:</h2>

<em>Reformatting the code snippet and giving it line numbers;</em>

1. var totals = [141.95, 212.95, 411, 10.95];

2. totals[2] = 312.95;

3. var totalsString = "";

4. for (var i = 0; i < totals.length; i++) {

5. totalsString += totals[i] + "|";

6. }

Line 1 creates an array called totals with four elements.

First element = totals[0] =141.95

Second element = totals[1] = 212.95

Third element = totals[2] = 411

Fourth element = totals[3] = 10.95

Line 2 replaces the value of the third element <em>totals[2]</em> = 411 with 312.95.

Therefore the array <em>totals = </em>[141.95, 212.95, 312.95, 10.95]

Line 3 creates an empty string called totalsString

Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length

totals.length = 4 (which is the number of items in the array totals)

This means that the loop cycles from i=0 to i<4

During cycle 1 when i = 0, the expression inside the for loop executes as follows;

totalsString = totalsString + totals[0] + "|" //substitute the values

totalsString = "" + 141.95 + "|"

totalsString = 141.95|

During cycle 2 when i = 1, the expression inside the for loop executes as follows;

totalsString = totalsString + totals[1] + "|" //substitute the values

totalsString = "141.95|" + 212.95 + "|"

totalsString = 141.95|212.95|

During cycle 3 when i = 2, the expression inside the for loop executes as follows;

totalsString = totalsString + totals[2] + "|" //substitute the values

totalsString = "141.95|212.95|" + 312.95 + "|"

totalsString = 141.95|212.95|312.95|

During cycle 4 when i = 3, the expression inside the for loop executes as follows;

totalsString = totalsString + totals[3] + "|" //substitute the values

totalsString = "141.95|212.95|312.95|" + 10.95 + "|"

totalsString = 141.95|212.95|312.95|10.95|

At the end of the execution, totalsString = 141.95|212.95|312.95|10.95|

Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for

12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A 0-6

Job B 6-(6+3) = 6-9

Job C 9-(9+1) = 9-10

Job D 10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A 0-6

Job C 6-(6+1) = 6-7

Job B 7-(7+3) = 7-10

Job D 10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A 0-1 until 14

Job B 2-(2+3) = 2-5

Job C 3-(3+2) = 3-5

Job D 9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A 0-2 , 7-9, 12-14

Job B 2-4, 9-10

Job C 4-(4+1) = 4-5

Job D 5-7, 10-12
