- Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.flip_matrix(mat:list)->list You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix: W R I T X H D R L G L K F M V G I S T C W N M N F Expected: W N M N F G I S T C L K F M V H D R L G W R I T X Matrix: L C S P Expected: S P L C Matrix: A D J A Q H J C I Expected: J C I A Q H A D JSubject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.
- Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values(see image) Using a loop to reach the end of the list, write a code segment that deletes all the nodes in the list. Ensure the code performs all memory ‘cleanup’ functions.Programming: C# (C sharp) without using "array, while and furthermore advance loop"
- please code in python Forbidden concepts: recursion, custom classes Create a program that finds all the prime numbers between 2 to 1000. As each is found, add it to the list, then print the list in an organized fashion.Merge and quick sort Implementation – Directed Lab Work1. Complete the recursive algorithm for merge sort part in the given data file, ArraySortRecursive.java. 2. Complete the implementation of quick sort by implementing the method partition in thegiven data file, ArraySortRecursive.java.3. Save the file as ArraySortRecursiveYourlastname.java. 4. Save the test driver program as DriverYourlastname.java and run the program and verify.Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screenb) In the same program, insert an element in the above ArrayList at index 2. The resulting Array Listmust be one element larger. Print the resulting list to the screen.c) In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.d) In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.e) In the same program, use a 'for' loop to print each element of the Array List to the screen.f) Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.
- A dynamic array is exactly as it sounds.Circular Array 1. Palindrome Use python Write a method/function that takes in a circular array, its size and start index and finds whether the elements in the array form a palindrome or not. Return true if the elements form a palindrome, otherwise, return false. Example: Input: [20,10,0,0,0,10,20,30] (start =5, size=5) Output: True. Input:[10,20,0,0,0,10,20,30] (start =5, size=5) Output: Falseclass Solution(object): def longestCommonPrefix(self, strs): result ="" for i in strs[0]: for j in strs[1]: for k in strs[2]: if i == j and i == k: result+=i if len(result) >0: return result else: return result IndexError: list index out of range for j in strs[1]: Line 5 in longestCommonPrefix (Solution.py) ret = Solution().longestCommonPrefix(param_1) Line 31 in _driver (Solution.py) _driver() Line 41 in <module> (Solution.py) can someone explain why this is wrong?
