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.
