Explanation:
I have attached the answer as an image. I can't upload the file as it requires a licensed product and I only used demo version. I can provide the file too if you can give me your vlsig file required to use full software. However, If you just copy along the images on your Visual Studio, you will easily create the files yourself. Answer is provided for both scenarios as part A and part B, one which stops after 1 iteration and the one which loops until 0 height is given.
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]
it mean for some people that have technology like a computer and there are some who don't have access to technology like phones, and tv's
Answer: A.The introduced species compete for resources more effectively than native species.
Explanation:
An introduced species is also called the exotic species and this is an organism which is not a native organism or specie and therefore isn't native to the place but rather it's being transported to the place through the activities of human being.
When the introduced species are introduced to a particular area, they compete with the natives for the available resources and often do this more effectively than the other native species.
Therefore, the correct option is A.
