Balanced sum

Design the function @suma_equilibrada(f)@ that, given a list of integers $f$, returns the smallest index $i$ such that the sum of the elements of $f$ from the first position until the position $i$ is equal to the sum of the subsequent elements. Note that $i$ has to be a valid position in the list. If this position does not exist, the function will return -1.
