Hello. My friends and I tried to solve this problem of this website.
But we could not. Can anyone please provide a proof of this problem? Thanks.
You will be given several intervals. Every input of an interval consists of 3 numbers ai,bi,ci where a and b are the starting and ending of the interval. From all the intervals you have to find a set of integers Z which have ci number of common integers between ai and bi . You have to find out the minimum size of Z.
