Output Format
If it is possible to cover the entire facade, output a single line containing the maximum number of party members who can leave their posts and confront Barlow as described in the problem statement.
If there is no group of party members who can cover the entire facade, output one line containing "'Salem's Lot is doomed." without quotes.
See the sample input for an example.
Sample Input 0 10 3 1 4 5 10 1 8
Sample Output 0 1
Explanation 0 Person 0 can cover the 1 to 4 range. Person 1 can cover the 5 to 10 range. Since 2 people are enough to hold the facade, they can send 1 person inside.
Sample Input 1 10 3 1 4 5 9 1 8
Sample Output 1 'Salem's Lot is doomed.
Explanation 1 Nobody in the party can cover the last meter of the facade, therefore 'Salem's Lot is doomed.
The actual code
def solve(L,n,coverage): # compute and return answer
L,n = list(map(int,input().rstrip().split(" "))) coverage = [list(map(int,input().rstrip().split(" "))) for i in range(n)] print(solve(L,n,coverage))
Transcribed Image Text:Father Callaghan has escaped 'Salem's Lot by sunrise. He had failed to save the town. The vampires had won.
Two years have passed. 'Salem's Lot is still infested with vampires, led by the insidious Kurt Barlow. However,
Father Callaghan has brought some backup. The former citizens of 'Salem's Lot who also barely escaped have
now joined him in taking back their home.
As they enter the town with their specialized vampire-killing gear, they now cornered the last of the vampires
in the fences of the Marsten house. The house is backed up against a hill so they can't escape through the
back. The only escape is through the facade of the house.
The house's facade extends L meters. Father Callaghan and his companions come up to a total of N people
that can barricade the facade. Each person can cover a specific part of the facade. They have decided that as
many of them as possible must enter the house to confront Barlow. This means they have to select as few of
them as needed to cover the entire facade (which means at least one person must be guarding all positions
from 1 to L) or else the vampires may be able to flank them.
Input Format
Input consists of one test case beginning with a line with two space-separated integers L and N.
L is the total length of the facade of the house.
N is the number of people in Callaghan's party.
N lines follow, the ith of which contains two integers A; and B; indicating the left and right bounds the ith
party member can cover respectively.
Constraints
2<L ≤ 10¹8
1≤ N≤ 3.105
1 ≤ A ≤ B ≤L
