You are given an array of N non-negative integers: A₁, A₂, ..., A_N. An alternating subsequence is a subsequence in which the indices of any two consecutive elements differ by exactly two in the original array. That is, if A_i1, A_i2, ..., A_ik is some subsequence, then for it to be an alternating subsequence, (i₂ - i₁ = 2), (i₃ - i₂ = 2), and so on should all hold true. Among all alternating subsequences, find the one which has maximum sum of elements, and output that sum.

Sample Output 1:

This

is

CSE110

Explanation: The second input which is the character '-', is used to split or divide the first input String 'This-is-CSE110' into 'This', 'is' and 'CSE110' which are printed individually in separate lines.

1. Open and read the countrycities.csv file.

2. Count and display the number of cities per country.

3. Count and display the country which is a member of the EU (EU = yes) and not a member of the EU (EU = no).

4. Find and display the country with the highest and lowest total population.

5. Count and display the country with a coastline (coastline = yes) and without a coastline (coastline = no).

Write a python function Write_String(fname, *list)  which take a list containing string elements and write them in a file myfile.txt until the string “finish” (not case sensitive) occur. The function then returns the contents written in file as a string. Before writing list elements in file, you also need to make a separate python function to check whether input list contains "Finish" or not. If not, then it should return error as shown in example.

 Write a python function Read_Prime(fname, list)  which takes a list of numbers as an input, use this number to write them in a file "primes.txt" . The function then read the file and return a list containing only prime numbers as shown in the example. Also, write the exception handling code to show the proper message.

def Read_Prime(fname, list_1):

    #write your code here

    return

#Call your function from main

list_1=[1,2,3,4,5,6,7]

fname = "primes.txt"

res = Read_Prime(fname, list_1)

print(res)
