Trial Assignment

• 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 output

– Submit as a zip file with name “0_LastName_FirstName.zip” and include:

• 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
