InputIterator find_if (InputIterator first, InputIterator last, UnaryPredicate pred);

first, last :range which contains all the elements between first
and last, including the element pointed by first but
not the element pointed by last.

pred : Unary function that accepts an element in the range
as argument and returns a value in boolean.

Return value :
Returns an iterator to the first element in the range
[first, last] for which pred(function) returns true. If
no such element is found, the function returns last.
