Write in Python:
A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes in word pairs that consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume the search name is always in the list.
Ex: If the input is:
Joe,123-5432 Linda,983-4123 Frank,867-5309
Frank
the output is:
867-5309
A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found.
Ex: If the input is:
3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank
the output is:
867-5309
Your program must define and call the following function. The return value of GetPhoneNumber is the phone number associated with the specific contact name.string GetPhoneNumber(vector<string> nameVec, vector<string> phoneNumberVec, string contactName)
Hint: Use two vectors: One for the string names, and the other for the string phone numbers.
Task 5
Write a Python program that takes numbers as input into a list, removes multiple occurences of any number and then finally prints a list without duplicate
values.
Hint: You may create a third list to store the results. You can use membership operators (in, not in) to make sure no duplicates are added.
Sample Input 1:
0, 0, 1, 2, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9, 4, 4
Sample Output 1:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Sample Input 2:
7, 7, 7, 1, 0, 3, 3, 55, 9
Sample Output 2:
[7, 1, 0, 3, 55, 9]

- 4. Let there are N numbers in a list and that list is said to be a UB Jumper if the absolute values of the difference between the successive elements take on all the values 1 through N-1. For example, 2 1 4 6 10 is a UB Jumper because the absolute differences between them are 1 3 2 4 which is all numbers from 1 to (5 - 1) or 4. Write a python program that takes a number sequence as input and prints whether it is a UB Jumper or Not UB Jumper. Input will stop after getting "STOP" as input. (Number order or absolute difference order doesn't follow any sequence.)

The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once.

Then, the last input integer will indicate the threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
