TL;DR:
Grid
simplifies to true, if and only if it is a 3x3 magic square.full explanation
Fifteen
is an array of length 15T
checks if an array of lengthA
+B
+C
is equivalent to an array of length 15, thus checking ifA
+B
+C
is equal to 15And
is simplifies toX
ifA
is true, else it simplifies tofalse
Df
checks ifA
andB
are Diffrent , simplifying toX
if they areGrid
first checks if every row, column and diagonal is equal to 15, then checks if every item is unique.
