Find f(n): nth Fibonacci number. The problem is quite easy when n is relatively small. We can use simple recursion, f(n) = f(n-1) + f(n-2), or we can use dynamic programming approach to avoid the calculation of same function over and over again. But what will you do if the problem says, Given 0 <...
