In a forest, there were 'x' bunnies, 50% male, and 50% female, all adults. Bunnies doubles every 15 days, 10% of the baby rabbits dies at birth. They mature after 30 days, 30% leave the forest, and rest becomes rabbits. In every 30 days , 25% dies off due to flu. If every bunny dies off, the bunny world ends.
Calculate the final number of bunnies alive after 1 year for any number of initial bunnies, x.
Input
Will be an integer number, the number of initial bunnies. Your program should read from the standard input
Output
Your program should write back to the standard output. When all bunnies die off, write 0 to the standard output.
Example
Test Case 1
444 (input)
0 (output)
Test Case 2
30000 (input)
56854 (output)

Please show your attempt, and describe any error messages you have encountered.

Hint - the information about 50% male, 50% female doesn't matter. There are no separate birth and death rules mentioned for males and females.

The general structure of the solution would probably be a for loop like this
for day=15:15:365
if mod(day,15)
%do 15 day birth/death update
end
if mod(day,30)
%do 30 day birth/death update
end
end
