Answer:
The solution code is written in Python 3:
- def modifyList(listNumber):
- posCount = 0
- negCount = 0
-
- for x in listNumber:
- if x > 0:
- posCount += 1
- else:
- negCount += 1
-
- if(posCount == len(listNumber)):
- listNumber.append(max(listNumber))
-
- if(negCount == len(listNumber)):
- listNumber.append(min(listNumber))
-
- print(listNumber)
-
- modifyList([-1,-99,-81])
- modifyList([1,99,8])
- modifyList([-1,99,-81])
Explanation:
The key step to solve this problem is to define two variables, posCount and negCount, to track the number of positive value and negative value from the input list (Line 2 - 3).
To track the posCount and negCount, we can traverse through the for-loop and create if else statement to check if the current number x is bigger than 0 then increment posCount by 1 otherwise increment negCount (Line 5- 9).
If all number in the list are positive, the posCount should be equal to the length of the input list and the same rule is applied to negCount. If one of them happens, the listNumber will append either the maximum number (Line 11 -12) or append the minimum number (Line 14-15).
If both posCount and negCount are not equal to the list length, the block of code Line 11 -15 will be skipped.
At last we can print the listNumber (Line 17).
If we test our function using the three sets of input list, we shall get the following results:
[-1, -99, -81, -99]
[1, 99, 8, 99]
[-1, 99, -81]
Answer:
1. =CONCATENATE(" John"," ","Smith")
2. =(" John"&" "&"Smith")
Explanation:
Given
Two separate strings; "John" and "Smith"
Required
2 separate formulas to concatenate both strings to form " John Smith"
There are several ways to concatenate strings in Microsoft Office Excel; one of the methods is using the concatenate function while the another method is using the traditional & operator.
Using the concatenate function, the formula is as follows
=CONCATENATE(" John"," ","Smith")
This function will combine the " John", " " and "Smith" to give a new string " John Smith" (without the quotes).
Using the traditional & operator may be a little bit difficult (and not frequently used) but the formula is as follows;
=(" John"&" "&"Smith")
The result will be the same as (1) above
