Answer:
Using word documents instead of paper can save lots of paper especially, when lots of people are doing that already. Using emails can reduce the amounts of letters being sent to people.
Answer:
Explanation:
The following pseudocode for this method using operations of the ADT list would be the following
swap(aList, indexI, indexJ) {
initialize temp_variable = Retrieve(indexI, aList)
Insert(Retrieve(indexJ, aList), indexI, aList)
Insert(Retrieve(indexI, aList), temp_variable, aList)
}
This code basically saves the aList index of i , into a temporary Variable. Then it sets the aList index of i to the value of the element in index of j. Then it does the same for the index of j with the tem_variable. If we assume that the indexes of i and j exist, then it can crash our entire program if those indexes are missing from the list when we try to access them.
