Recently, Goffi is interested in squary partition of integers.
A set \(X\) of \(k\) distinct positive integers is called squary partition of \(n\) if and only if it satisfies the following conditions:
[ol]
the sum of \(k\) positive integers is equal to \(n\)
one of the subsets of \(X\) containing \(k - 1\) numbers sums up to a square of integer.[/ol]
For example, a set {1, 5, 6, 10} is a squary partition of 22 because 1 + 5 + 6 + 10 = 22 and 1 + 5 + 10 = 16 = 4 × 4.
Goffi wants to know, for some integers \(n\) and \(k\), whether there exists a squary partition of \(n\) to \(k\) distinct positive integers.
