Maximum ⬀
Consider the sequence of numbers aᵢ
, i = 0, 1, 2, …
, which satisfies the following requirements:
a₀ = 0
a₁ = 1
a₂ᵢ = aᵢ
a₂ᵢ₊₁ = aᵢ + aᵢ₊₁
for every i = 1, 2, 3, …
.
Write a program which for a given value of n finds the largest number among the numbers a₀
, a₁
, …, aₙ
.
You are given several test cases (not more than 10
). Each test case is a line containing an integer n
(1 ≤ n ≤ 99 999
). The last line of input contains 0
.
For every n
in the input write the corresponding maximum value found.
