Important Notice for HKOI2003 Finalists
issued by The HKOI Organizing Committee
To help HKOI2003 finalists get familiar with the file input and output
requirements of the Final Event, an "open question" is listed below.
This question will reappear in HKOI2003 Final Event with slight
modifications.
Contestants are advised to practise the problem before the competition so as
to understand how to read from and write to files in Pascal. Please pay
particular attention to the strict requirements in output format in the
competition. Output files of ALL HKOI Final questions should comply
with the following rules:
- Output data should be formatted EXACTLY as described in the question.
- Each line, including the last output line, must be ended with a new-line
character.
- Characters immediately preceding a new-line character must not be white
spaces (i.e. no trailing spaces in a line).
- There should not be any additional line(s) (including but not limited to
empty line with just a new-line character) after the last output line (i.e. no
trailing lines in a file).
Problem 0: Enumeration
Program name : ENUM.EXE
Input file : INPUT.TXT
Output file : OUTPUT.TXT
Execution Time Limit : 1 second
Problem
Write a program to read an integer N and output all integers from 1 to
N2.
Input
The input file INPUT.TXT contains a single
integer N, 1 <= N <= 10.
Output
The output file OUTPUT.TXT consists of N lines,
each containing N integers, separated by a single space.
The integers are 1 to N2 in ascending order.
An integer is always greater than the one on its left and all numbers in the row above, if applicable.
Sample Input
4
Sample Output
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
