How to swap two variables, without using third variable ?
Answer Posted / perl guru
($a,$b)=($b,$a)
....this is how we do in PERL....Ha Ha Ha pretty cool !!!!
And BELIEVE me it works not only for NUMBERS but also for
STRINGS, ARRAYS or any Data Structure or any garbage
value....this is mine Challenge.....
None of the any programming language can come close to PERL
in this much of SIMPLICITY and ROBUSTNESS....just one line
does the Magic....
Again I would say the Question itself is very silly one "How
to swap two variables, without using third variable
?"....and I see alot of stupid Answers posted here....
Everyone posting the answer is assuming that Question is
about swapping INTEGER NUMBERS....I would like to ask what
if I provide FLOATING POINT NUMBERS, NEGATIVE NUMBERS, REAL
NUMBERS, and surely it does not work for STRINGS....
That is why I say "Perl is immensely powerful. If you think
something can't be done, the problem is likely to be it is
beyond your ability, not that of Perl."
Welcome to the world of PERL....its more precious than PEARL....
