Re: [algogeeks] Re: difference x
@ jai nice solution I think for O(n) solution we will have to use extra array. Otherwise we will have to do this in O(nlogn). Correct me if i am wrong.

[algogeeks] Re: difference x
There is simple solution of the similar problem: given sorted array, find two values which sum up to X. It can be solved with two pointers, such approach has been discussed on the forum some months ago. Your problem is similar. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group. To post to this group, send email to algoge...@googlegroups.com.

@saurabh u might be a genius bt for ur kind information this is the group for learners... this group is a place where people come to learn new tricks, put their ideas and ask doubts.. so it would have been better if u had put your response rather than discouraging anyone from asking doubts.. while putting this problem i had the nlogn approach in my mind as pointed by vivek. but i wanted a better approach O(n) as it exist for the sum problem where sum=x. so i posted it here.. it does not mean if u know a solution than the problem is solved. there is always a chance of optimization which u can learn only by discussing... u could simply delete mail if u find it so simple.. and everybody has his own style.. now a days i was solving algorithm problems from various blogs and sites so i posted all my doubts in one go...

Re: [algogeeks] Re: difference x
make another array(B) from (A) with all elements negated now find one element from B and one from A whose sum is x or -x. This can ofcourse be done in O(n). -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group. To post to this group, send email to algoge...@googlegroups.com.
