TJANDRAS - Tjandra 19th birthday (EASY)
This day (7 February 2013) is my 19th birthday So, I want to celebrate it on SPOJ by making this EASY puzzle problem.
This game/puzzle is about matches, given n matches, your task is to arrange the matches (not necessarily all) such that number of rectangle (any size) is maximum.
First line there is an integer T≤100 then T lines follow, each line contain an integer n<1.000.000.000.
For each test case, output required answer (maximum number of rectangles)
-->First test case: No rectangle can be formed with only 3 matches
-->Second test case: Only one rectangle can be formed with 4 mathes
-->Third test case:
there are max 3 rectangles (2 size 1x1, 1 size 2x1) can be formed with number of matches<=8, here is one of the mathes formation:
-->Fourth test case:
there are max 9 rectangles (4 size 1x1, 2 size 2x1, 2 size 1x2, 1 size 2x2) can be formed with number of matches <=12, here is one of the formation:
-->Fifth test case:
there are max 12 rectangles (5 size 1x1, 3 size 2x1, 1 size 3x1, 2 size 1x2, 1 size 2x2) can be formed with number of matches <=15, here is one of the formation:
Time limit≈150x my program speed, Enjoy this birthday party game, I set this problem such that semi naive solution will pass..
Tjandra can you help me? I dont understand why my code doesnt work. For first 30 numbers it works.

@VenkateshP: Your solution isn't optimal, there are better configuration..
GREEN finally :D
Hi @Tjandra I'm getting Wrong Answer, Can you please check at my submission(id 11692407)
YESSSS Finally GREEEN green green!!
this problem is humungously tough without paper.... with a pen and paper takes a few minutes. I now truly understand the EASY tag, Tjandra
Ok, it sounded like maybe you were questioning the wording of this problem, rather than just suggesting a new related problem.
there is two ways to arrange
I think it's clear from the explanation what we are meant to count, and what kinds of arrangements are allowed.Last edit: 2013-05-29 09:44:20
