Floor Crossed Integer Quintuplet Query (Posted on 2023-08-04) Difficulty: 3 of 5
Determine all possible quintuplets (p, q, r, s, t) of positive integers that satisfy this equation:

⌊(p+q)/3⌋2 +⌊(q+r)/3⌋2 + ⌊(r+s)/3⌋2 + ⌊(s+t)/3⌋2 = 38

*** ⌊p⌋ is the floor function. ie. the greatest integer less than or equal to p.

****** Adapted from a problem appearing at an Austrian Mathematical Olympiad in 2007.

**** Computer program assisted solutions are welcome, but a semi-analytic methodology, that is: hand calculator and p&p, is preferred.

I recently used https://scamfighter.net/review/5staressays.com for my essay, and I must say, they exceeded my expectations! The quality was outstanding, delivered on time, and their customer support was fantastic. I highly recommend 5staressays for top-notch academic assistance.
