Description
Write a program that prints the multiplication of two selected numbers from a line
- First line of input contains the number of lines to follow
- First number of each line, n>=4 and n<=1000, contains the number of integers that follow in the line
- Those n integers (each integer >=0; <=1000) follow till the end of the line, and should be stored (except the last two) in an array using index numbers 1…n-2
- The last two integers x, y (x,y>=1 & x,y<=n-2) in the line is the index
(starting from 1) of the integers from the line to multiply and print Example: (colors are just for visualization):
Input: Output:
3
- 13 2 5 1 3
- 5 3 6 7 4 2
9 7 12 2 14 5 7 9 6 3
Input/output in Java
- Use Standard I/O to read input and write the result For Java, input: System.in, output: System.out
- To read numbers, one option is:
- Use a single Scanner object Scanner sc = new Scanner(System.in);
- Use nextInt()over and over to read integers
number = sc.nextInt(); • To print numbers: System.out.println(x);
- “Do Not”s
- Do not read from a disk file/write to disk file
- Do not write anything to screen except the result
- Ex: Human centric messages (“the result is”, “please enter..”)
- Automated grading via script will be used for checking correctness of your outputde:
- Java source code in a single file java (all lower case letters!)
- The file should have your name in a comment in the first line
- Remember: in Java, class name should match the file name, and is case sensitive
- Please do NOT create your own packages
- Do NOT place the file into a folder – just zip the file
- Use standard I/O to read input (System.in, System.out) and output Make sure the program compiles
