What's the safest way to iterate through the keys of a Perl hash?
...ng the expected resulting hash:
(a => 1, A => 2, b => 2, B => 4)
But using each() to do the same thing:
%h = (a => 1, b => 2);
keys %h;
while(my($k, $v) = each %h)
{
$h{uc $k} = $h{$k} * 2; # BAD IDEA!

Time complexity of Euclid's Algorithm
...o drop below 1. The total number of steps (S) until we hit 0 must satisfy (4/3)^S <= A+B. Now just work it:
(4/3)^S <= A+B
S <= lg[4/3](A+B)
S is O(lg[4/3](A+B))
S is O(lg(A+B))
S is O(lg(A*B)) //because A*B asymptotically greater than A+B
S is O(lg(A)+lg(B))
//Input size N is lg(A) + lg(B...
