you are right, fixed it

in majority, you donāt use 1 as modulo but yes, you are right

good post i like it

Itās not visible, can you share it somewhere else? Probably there is overflow in your codeā¦

Hey,i am not getting how your recursion takes %(100000007) at every recursive step to avoid overflowā¦Can you explain this little bit.I mean to say how recursion work here?Does it calculate a^b and then calculate %(100000007) or it calculates ((a1%(100000007)*(a2%100000007)ā¦)%(100000007).If the answer is latter can you please explain how

actually this tutorial is awesomeā¦I m stucked how can any1 explain so simpleā¦I want to learn programming , algorithm in your guidence please provide me some source to read your blog, tutorial any material produced by you or any1 like youā¦

thanks for appreaciationā¦

can somebody explain this solution

pow function is costly. It can potentially increase runtime by a factor of at least 5. I got TLE on using `pow(2,x)`

when T.L. was 2 seconds, but replacing it with `1<<x`

got AC in 0.2 secs.

Its Basically reducing the Power which just enlarge the number but reduces the no. of iterationsā¦

can u please share the code for this function

Its a standard cpp function. You can google it.

when i am running this above code in codeblocks it is showing conflicting types of fast_exp i am not getting why this is happening can someone please help.

use powl in place of pow

thank me later
