And I was expecting whole the time the block of commands to calculate the length, why it takes him so long to write it 😃
Nice work

[@PortfolioCourses]

Thank you! :-)

Nice job! It looks like n^2 complexity. Is it possible to make it more efficient?

[@PortfolioCourses]

Yes, there's a few ways. :-) One quick optimization would be to 'break' in the inner-loop as soon as a match is found. Another optimization would work if we knew the range of ints... we could create an array of bools (one for each possible int) and set the index for an int to true if a match is found, then checking to see if a match is found is a matter of checking that index, making the problem O(n) complexity (but taking up more space too).

[@baotang6436]

anyone help me
if(!match_found) is if(match_found == false)
is it right ?

[@poisonmods]

Ur back

[@PortfolioCourses]

Yep! :-) Hoping to get back to posting at least semi-regularly now.
