Which of the following represents the factorial function?
A) Function Numeric unKnown(Numeric num)
// Call function recursively until reaching 0 or 1
If num == 0 Or num == 1 Then
Return num
Else
Return unKnown(num - 2) + unKnown(num - 1)
End If
End Function
B) Function Numeric unKnown(Numeric num)
// Base case returns 1
If (num == 1) Then
Return 1
Else
Return (num * num) + unKnown(num - 1)
End If
End Function
C) Function Numeric unKnown(Numeric num)
// Declare variables
Declare Numeric fact = 1
Declare Numeric index // loop index
// Loop
For index = num to 1 Step -1
Fact = fact * index
End For
Return fact
End Function
D) Module unKnown(Integer n, sourcePeg, targetPeg, sparePeg)
If (n > 0) Then
MoveDiscs(n - 1, sourcePeg, sparePeg, targetPeg)
// Move disc from sourcePeg to targetPeg
MoveDiscs(n - 1, sparePeg, targetPeg, sourcePeg)
End If
End Module
