I had a hard time understanding this sentence, but eventually I think it means: 'A bomb in the sequence should not set off another bomb that appears later in the sequence'. Correct, but unnecessary: how could you manually set off a bomb that has already exploded?

I agree with the fact ...

Note that the first integer in the input is the number of cases. The input description does not explicitely state this. Treating it as the 'n' of the first case (and reading input until EOF) gives the right answer for all example cases, but will get WA on the judge.

Hint:

M = 2000000
N = 2
Books: 1000000 1 1000000

I do something like

Code: Select all

int a, b;
char c;

scanf("%d%c", &a, &c);
while(c != '\n' && b == 2)
	b = scanf("%d%c", &a, &c);

But you have to be sure that there is no trailing spaces (usually there arent).
