Hi codeforces,
I'm trying to solve problem 372A ( Counting Kangaroos is Fun ), but i can't figure out what's wrong with my solution #50057680. What i am trying to do is sort the array and use two pointers to get the answer but i'm stuck on test case 6?
Your asumation is wrong. For exemple take this test. 4 1 1 2 4
Your code gives 3 but the corect answer is 2; I will let you figure it out why.
Try to find another solution. If not, you can look at the tutorial. It's a easy and corect solution to this.
I think in the test case you gave the correct answer is indeed 3 ?
No, man. 4 takes 1 2 takes 1
Total left=2
The first 4 from the example is the number of Kangaros. The array is 1 1 2 4
