Given an expression in the form of a string, solve for x. The highest power
of x in the expression will be equal to 1. Operators allowed are +, * and
-. These are all binary operators. So, 2x would be written as 2*x. Every
operator will be followed by a single term or a constant.
For example,
you dont need that much to do this problem
modify merge method in mergesort to calculate the sum in nlgn
think about it it's quite easy
you must have heard of Count Inversion problem , this is similar to that

I dont know if it can be solved in O(n). But O(nlogn) can be done using
BIT. Refer topcoder tutorial for Binary indexed trees.

@anshu- your code works fine.but can you plz explain how you concluded
this codei mean what's the logic behind to check myset.size() psize
?? ...as you are assuming that it will be increase string and check
until this condition satisfies ??

I was not sure that for every number that has 3 in its unit place has one
multiple which has all one. So I used that is if the remainder is coming
that already appeared stop there coz it will make stuck in a loop.
for ex. remainders are
1 3 19 23 37 1 3 19 that will repeat.
but it in
23 has 3 in its unit place but it is not multiple of 111 or 11 or .
will u pls elaborate on the problem statement?

thanks a lot for replying to the post... but try posting algorithm rather

For every number that has 3 in its units place has one multiple which
has all one's i.e. 111 is
such multiple and 13 has a multiple 11. Write a program to find
such multiple for any
number that has 3 at its units place.

I have a software problem and I'm searching for a solution but tried
different algorithm approach and nothing came out.
I'm not very familiar with all the graph algorithms and I hope there
is already a way to solve this kind of problems in polynomial time.
I need the algorithm for different task
Sort the array first and then check for the given conditions.
Sorting the array takes O(nlog n) in the worst case.
