I'm a fairly new programmer (just started yesterday!). I decided to tackle Project Euler #2 today, as I did #1 yesterday without many problems. I came up with what seems to me to be a working solution, but I feel like I did it in an exceedingly ugly way. Could anyone suggest improvements to my code and/or logic?
Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
fib = 1 fib2 = 2 temp = 0 total = 0 while temp <=4000000: temp = fib2 if temp % 2 == 0: total += temp temp = fib + fib2 fib = fib2 fib2 = temp print total
I just sort of used my
temp variable as a holding ground for the results, and then juggled some variables around to make it do what I wanted... Seems like quite a mess. But it does result in
4613732, which seems to be correct!
