Consider the Recursive Square Method Shown Below That Takes a Non-Negative

question 43

Multiple Choice

Consider the recursive square method shown below that takes a non-negative int argument.
Public int square(int n)
{
Return square(n, n) ;
}
Public int square(int c, int n)
{
If (c == 1)
{
Return n;
}
Else
{
Return n + square(c - 1, n) ;
}
}
Assume that the last return statement is changed to this:
Return n * square(c - 1, n) ;
What would a call to square(4) return?

• A) 4
• B) 16
• C) 64
• D) 256

Definitions:

Singlet

A term used in spectroscopy to describe an energy state of an atom or molecule where all electron spins are paired, resulting in zero net magnetic spin.

NMR

A powerful technique for determining the physical and chemical properties of atoms by studying their magnetic properties related to nuclear spin.

Triplet

A term used in quantum mechanics and spectroscopy to describe a system or state with three closely related energy levels or components.

Multiplet

In spectroscopy, refers to a pattern of two or more peaks that are closely spaced in the spectrum, indicating the presence of equivalent or similar atomic environments.
