ある数のベクトルが与えられた場合、そのベクトルの要素の一つが他の要素の二乗であれば true を返し、それ以外の場合は false を返すようなコードを書いてみましょう。

例:

 入力が  a = [2 3 4] のとき、
 出力 b は true になります。

 2の2乗は4であり、ベクトル内に2と4の両方が含まれているため、出力は true になります。

This appears to be duplicating an error in the original Problem: according to the problem specification, having an input of [1] should yield a result of "false", as there is no OTHER element to compare the 1 to! You can easily fix this inconsistency by either --- changing your problem specification (mention that you can compare to all vector elements, not just the 'other' elements) or --- by changing the correct result to "false" in your Test Suite.
