Canadian Computing Competition: 2003 Stage 1, Junior #2

Roy has a stack of student yearbook photos. He wants to lay the pictures on a flat surface edge-to-edge to form a filled rectangle with minimum perimeter. All photos must be fully visible. Each picture is a square with dimensions 1 unit by 1 unit.

For example, he would place 12 photos in the following configuration, where each photo is indicated with an X.


Of course, he could orient them in the other direction, such as


which would have the same perimeter, 14 units.

Your program should repeatedly read a positive integer C, the number of pictures to be laid out. For each input, it should print the smallest possible perimeter for a filled rectangle that is formed by laying all the pictures edge-to-edge. Also print the dimensions of this rectangle.

You may assume that there are less than 65\,000 photos. An input value of C = 0 indicates that the program should terminate.

Sample Input


Sample Output

Minimum perimeter is 40 with dimensions 10 x 10
Minimum perimeter is 16 with dimensions 3 x 5
Minimum perimeter is 56 with dimensions 13 x 15

    To rnpmat08, your output says "Minimum Perimeter" instead of "Minimum perimeter".

    My code is working perfectly fine in PyCharm and I also used the sample inputs (which outputted correctly), however I get a IR when I submit my solution. Does anybody what could be causing this problem?

    What is the test case?? On the first line I got

    Minimum perimeter is 32 with dimensions 10 x 6

    Isn't it correct (for 60)?

      Try switching the 10 and 6 i.e. Minimum perimeter is 32 with dimensions 6 x 10

    Edit 2 Now: I used lowercase X, tweaked my code to make sure an input of 1 would give the correct answer, yet I'm still getting WA (Wrong Answer) and it says my output is just a snippet of what's expected. It works perfectly fine in my IDE, but why doesn't it pass DMOJ's judge test?

    Can someone check my code, when I try the input on PyCharm it works fine but it doesn't seem to work on DMOJ

      notice that you are outputting "Minimum perimeter is 32.0 with dimensions 6 x 10" indicating that you did division with "/" which returns a float instead of integer division "//" (line 13 in your most recent submission).

      as a side note i think they prefer people asking for help on the dmoj discord instead of the comment section

    I only seem to be getting 80/100 with only one test case even though it appears to meet all the requirements? Anybody got any ideas?

    Edit: Nvm my code did not work for when there was only 1 picture
