QUESTION
A friend gave me this problem as a challenge, and I've tried to find a problem like this on LeetCode, but sadly could not.
QuestionMy approachGiven a line of people numbered from 1 to N, and a list of pairs of M enemies, find the total number of sublines with people that contain no two people that are enemies.
Example:
N = 5, enemies = [[3,4], [3,5]]
Answer:
9
Explanation: These continuous subintervals are:
[1,1], [2,2], [3,3], [1,2], [2,3], [1,3], [4,4], [4,5], [5,5]
We define a non-conflicting interval as a contiguous interval from (and including) [a,b]
where no two people are enemies in that interval.
Working backwards, if I know there is a non conflicting interval from [1,3]
like in the example given above, I know the number of contiguous intervals between those two numbers is n(n+1)/2
where n
is the length of the interval. In this case, the interval length is 3
, and so there are 6
intervals between (and including) [1,3]
that count.
Extending this logic, if I have a list of all non-conflicting intervals, then the answer is simply the sum of (n_i*(n_i+1))/2
for every interval length n_i
.
Then all I need to do is find these intervals. This is where I'm stuck.
I can't really think of a similar programming problem. This seems similar, but the opposite of what the Merge Intervals problem on leetcode asks for. In that problem we're sorta given the good intervals and are asked to combine them. Here we're given the bad.
Any guidance?
EDIT: Best I could come up with:
Does this work?So let's define max_enemy[i]
as the largest enemy that is less that a particular person i
, where i
is the usual [1,N]
. We can generate this value in O(M)
time simply using a the following loop:

Answered 2020-Jul-13 at 15:21There's a cool visual way to see this!
Instead of focusing the line, let's look at the matrix of pairs of players. If i
i and j
are enemies, then the effect of this enemiship is precisely to eliminate from consideration (1) this interval, and (2) any interval strictly larger than it. Because enemiship is symmetric, we may as well just look at the upper-right half of the matrix, and the diagonal; we'll use the characters
- "
X
" to denote that a pair is enemies, - "
*
" to indicate that a pair has been obscured by a pair of enemies, and - "
%
" in the lower half to mark it as not part of the upper-half matrix.
For the two examples in your code, observe their corresponding matrices:
