- Java Objective:Design and implement simple matrix manipulation techniques.Details:Your java program should use 2D arrays to implement simple matrix operations.Your program should do the following:• Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order• Print M1 to the console; make sure you format as a matirx• Repeat the previous steps for a second matrix M2• Create a matrix M3 that is the transpose of M1 and print it to the console• Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message.• Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements:• Use a helper method for reading a positive integer using an input validation loop.• Use a helper method for printing…arrow_forwardUsing C++ Programming language: Assume you want a function which expects as parameters an array of doubles and the size of the array. Write the function header that accepts these parameters but is defined in such a way that the array cannot be modified in the function.

- write a code in C++ You work for a streaming analytics company and have been tasked with writing a program that analyzes views and likes on a series of YouTube videos. Code a modular program that uses parallel arrays to store views, likes, and like percentages for a series of videos. The program must do the following: The program must first ask the user for the number of videos that will be selected from YouTube. This must be done using a function that is called. For each video, the program must use random numbers to generate the number of views, likes, and the like percentage and store each value in a series of parallel arrays. These arrays must NOT be declared globally. These arrays also must be populated using a loop that calls a series of functions to generate the views, likes, and like percentage. The following arrays must be declared: views[] - an array of type long to hold the randomly generated views each YouTube video gets likes[] - an array of type long to hold the…arrow_forwardHelp now please Pythonarrow_forwardDeclare 2D array whose size and elements must be according to the desire of user then perform the following functions on it Display a lower triangular matrix.

- Write a function in C language that will take a 2D Array of size 3x3 from the user. Your Program should: 1. Prompt the user to enter 2D array of size 3x3. 2. Calculate the sum of all rows. 3. Calculate the sum of all columns 4. Return 1 if the sum of all rows is greater than sum of all columns, 0 otherwise. Your main program should print the result based on the returned values.arrow_forwardIn C++ language Write a function that takes a 1 Demensional array and an integer n and reutrns the number of times 'n' appears in the array.
