AGGRCOW - Aggressive cows
Farmer John has built a new long barn, with N (2 <= N <= 100,000)
stalls. The stalls are located along a straight line at positions
x1,...,xN (0 <= xi <= 1,000,000,000).
His C (2 <= C <= N) cows don't like this barn layout and become aggressive towards each other once put into a stall. To prevent the cows from hurting each other, FJ wants to assign the cows to the stalls, such that the minimum distance between any two of them is as large as possible. What is the largest minimum distance?
t – the number of test cases, then t test cases follows.
* Line 1: Two space-separated integers: N and C
* Lines 2..N+1: Line i+1 contains an integer stall location, xi
For each test case output one integer: the largest minimum distance.
1 5 3 1 2 8 4 9
FJ can put his 3 cows in the stalls at positions 1, 4 and 8,
resulting in a minimum distance of 3.
AC in One Go!!!
AC in 3rd attempt, was confused whether 0 will answer for maximizing the minimum distance :))
My first AC in one Go !! :')
I have been stuck on this question for ages, finally did it!! for those who are still stuck can go check out allocation of pages problem, the question is different but the concept is same. don't leave the question coz this is a great question for binary question.
what are the contraints of t ? they should clearly mention that in question.
Test Cases :
got WA. i need more test case as i am getting 3 for given input
The best question to learn binary search!!!
