Step 1: Recall the history of \( \texttt{C++} \).
\( \texttt{C++} \) was developed by Bjarne Stroustrup starting in 1979. His goal was to add object-oriented programming features to the C language.
Step 2: Understand the name “\( \texttt{C++} \)”.
The name itself is a programmer’s joke. The \( \texttt{++} \) operator in C is the increment operator, which adds one to a variable. So, “\( \texttt{C++} \)” implies that it is the next step up from C, or “C with additions.” It was initially called “C with Classes.”
def fun(L, i=0):
if i $>=$ len(L) - 1:
return 0
if L[i]> L[i+1]:
L[i+1], L[i] = L[i], L[i+1]
return 1 + fun(L, i+1)
else:
return fun(L, i+1)
data = [5, 3, 4, 1, 2]
count = 0
for _ in range(len(data)):
count += fun(data)
print(count)
A recursive function is given:
def mystery(n):
if n $<=$ 0:
return 1
else:
return mystery(n-1) + mystery(n-2)
Find the value of mystery(4).
