Expert Solution & Answer
Chapter 1.2, Problem 2QE
Explanation of Solution
Given Steps:
- Step 1:
- Move the contents of cell number 2 to cell number 3.
- Step 2:
- Move the contents of cell number 3 to cell number 2.
Errors in given sequence of steps:
- The Step 1 moves the contents of cell number 2 to 3.
- It deletes the value in cell number 2 and is been copied into cell number 3.
- The Step 2 moves contents of cell number 3 to cell number 2.
- It moves the value in cell number 3 to 2.
- In this case, the old value of cell number 2 only will get copied in this case.
- To rectify this, a cell is to be considered for temporary storage, suppose the cell is cell 4...
