1. Write a Python program that takes an array of integers as input and calculates the sum of all the elements in the array. 2. Write a Python program that takes an array of integers as input and finds the maximum and minimum values in the array. 3. Write a Python program that takes two arrays of integers as input and calculates their element-wise sum. The two arrays should have the same length. 4. Write a Python program that takes an array of integers as input and removes all duplicate elements, keeping only the unique elements in the array. 5. Write a Python program that takes an array of integers as input and sorts the elements in ascending order. 6. Write a Python program that takes an array of integers as input and checks if the array is sorted in non- decreasing order. 7. Write a Python program that takes an array of integers as input and calculates the average (mean) of all the elements in the array. Instructions: -Write the algorithm before writing the code - For each question, write a separate function that solves the problem. -Test your functions by calling them with different input arrays in the main program. - You can use any built-in functions or methods available for arrays in Python.
