Sorry I am new in Julia , This is my Fibonacci numbers function : > global fib_cache = Dict{BigInt, BigInt}(0 => 0, 1 => 1) > function fib(n::Integer) > global fib_cache > if haskey(fib_cache, n) > fib_cache[n] > else > fib_cache[n] = fib(n-1) + fib(n-2) > end > end The following function is a sho…

Not sure if this is an exercise or you just want it to work. If the latter, you may want to look at the Memoize package, which I described and demonstrated the usage of in a recent StackOverflow answer: https://stackoverflow.com/questions/60997656/how-does-this-recursive-function-in-julia-work/6099…

Just for fun, here’s an iterative version instead which is clearer and more efficient: function fib(n::Integer) n < 1 && return big(0) m = length(FIB_CACHE) if m < n resize!(FIB_CACHE, n) for i = m+1:n FIB_CACHE[i] = FIB_CACHE[i-1] + FIB_CACHE[i-2] en…

Thank you for your explanation, Yes this is a part of an Exercise. but actually the problem is when I running this code in Julia global fib_cache = Dict{BigInt, BigInt}(0 => 0, 1 => 1) function fib(n::Integer) global fib_cache get!(fib_cache, BigInt(n), fib(n-1) + fib(n-2)) end i got LoadError: St…

Did you look at your classmate’s post ? The problem is explained clearly by Henrique . Edit: I see now that you responded to Henrique in that thread. Let’s take it there.

Yes , and you can also check my reply to him . the problem is not related to Negative numbers as he explained. the code doesn’t work in general even if for a positive number

This is exactly the same code in Why is this code not working?. Homework problem?
