This code defines a function population
that takes an integer input n
and calculates the number of operations required to reduce n
to 0
based on a specific process. Here's what the code does step by step:
-
Initialization:
- An integer variable
con
is initialized to0
. This variable is used to count certain operations during the process.
- An integer variable
-
While Loop:
- The loop continues as long as
n
is not equal to0
.
- The loop continues as long as
-
Odd Check:
- Inside the loop, the function checks whether
n
is odd (n % 2 == 1
):- If it is odd, it performs the following operations:
- Update
n
to(n / 2) + 1
. (This effectively dividesn
by 2 and rounds it up.) - Increment the variable
con
by 1.
- Update
- If it is odd, it performs the following operations:
- If
n
is even, it simply updatesn
ton / 2
(integer division).
- Inside the loop, the function checks whether
-
Printing and Return:
- After the while loop is complete (i.e., when
n
becomes0
), the function prints the value ofcon
to the console. - Finally, it returns the value of
con
.
- After the while loop is complete (i.e., when
Key Observations:
- This code essentially traverses a sequence where even numbers are halved, and odd numbers are also halved but adjusted upwards (via the
+1
) and counted as an operation. - The variable
con
counts how many times this "odd adjustment" (n % 2 == 1
) occurs during the process.
Example:
If you call population(5)
:
- Initial
n = 5
(odd): Updaten = (5 / 2) + 1 = 3
, incrementcon = 1
. - Now
n = 3
(odd): Updaten = (3 / 2) + 1 = 2
, incrementcon = 2
. - Now
n = 2
(even): Updaten = 2 / 2 = 1
. - Now
n = 1
(odd): Updaten = (1 / 2) + 1 = 1
, incrementcon = 3
. - Now
n = 0
(loop terminates).
Output: 3 (as this is the number of odd adjustments made during the process). The function then returns 3
.
Purpose:
The function seems to perform a specific transformation on the number n
, and con
reflects the number of odd-number operations during the reduction to zero.
