5.19 Swapping of 2 Numbers in Easy way

In this video we will see how to swap 2 numbers in easiest way. We use a new formula: b = a+b-(a=b) to swap 2 numbers. we first solve round brackets then the rest.
Example: a=5 b= 6
b= 5+6-(a=6)
so, b= 11-6 = 5
therefore. a=6 and b = 5

Another trick you can do is a=a^b^(b=a) or a^=b^(b=a) if you desire that notation. This form also helps understand why the xor trick works when swapping bits since a gets set to a xor b xor a where the two a's in the xor will cancel out leaving the a = b, and at the end we directly set b = a as the last preformed operation requiring b.

Best video I have ever seen on KZbin. So easy way. Just one line solution. Great man.

[@SmartProgramming]

nice explanation sir, way of explanation is so nice, keep it up 👍👍

[@nilesh122n]

perfect,it is new logic

[@pitaji_badewale]

but in expression b=a+b-(a=b), why the value of first a is still 5 while the second one already assigned to 6??

[@mollasakil694]

Best technique...I never thought about itt

[@soniasu2744]

great tutor

[@shuvshaw9594]

very helpful

[@sayanmukherjee8563]

Sir how in one line the left a holds the value 5 and the right a holds the value 6.I mean to say when (a=b) is written the left a won't change its value?

[@moorgoolean]

Suscribed!

[@theAnalyticGuy]

This wont work if values of A and B are near Integer.MAX_VALUE. There will be overflow because we are adding.

[@mayanksingla492]

if brackets will be resolve first then 1st "a" should also have 6 value but it has 5, how?

[@snehalgavate3182]

This works too ☺️--->

[@archanamharish568]

cant we just swap while printing a and b like this??system.out.print(b+" "+a);

[@nidhisharma-wf3lv]

For A=5, B=10 short formula is not working

[@sarveshkhire415]

We can also do this to swap

[@francescopiazza4882]

gulp!

[@tummalaramakrishna5725]

we can also swapping using new varble

[@thespiritualjourney369]

previous way was a lot easy than this. This is not at all easy. Its more complicated.
