* Namely we can make BBQ with A ingredients when length A is shorter than B.
* For example, sticks that length 10 and 7, can make 1 BBQ with 7 ingredients cause 7 < 10.
* In other words, we can solve this problem just using sorting, and just get the odd number of values.
*
* ex) 3 10 8 6 can ordered
* 3 6 8 10, and we know that
* 3<6 and 8<10
* so the answer is 3+8 = 11.
* Of course, we can make the BBQ like 3 and 10, 8 and 6. but
* if this will be 3<10 and 6<8, so the max number of ingredient is 3+6 = 9.
