CSc 2720 - Data Structures: Assignment 1 [100 points] How to Submit: Turn the .java file in Folder Assignment 1 in iCollege no later than 11:00 p. m. ET on 01/27/2021 Notes: 1. Do not use any library for matrix multiplication. 2. Always use comments to explain your program. 3. No copying allowed. If it is found that students copy from each other, all of these programs will get 0. 4. You must use matrix. java as the program name; otherwise, you will lose 10%. Requirements: You are to write a program name matrix. java that makes the dot products of 2 arrays. 1. Your program should prompt the user for the dimensions of the two squares matrices, making sure that the user input is equal to 50. 2. If the above is not met, prompt the user for a new value. 3. Now generate random integer numbers (ranging from 0 to 50) to fill both matrices. 4. Display these two matrices on the screen. 5. Multiply the two matrices and display the result on the screen. 6. Insert a clock to see how long it would take to multiply these two matrices and display the time (with a message to this effect). 7. Prompt the user asking if they want to repeat the program. A simple example of program output (here matrix dimension is 4, your should be 50):

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.
