Dhaka Regional ACM ICPC 2016 Mock Contest Solution D - Box Sorting

D. Box Sorting

Score: 1

CPU: 1s
Memory: 1200MB

You are constantly getting threats from your mom to tidy up your desk. On top of your desk, there are lots and lots of cubic boxes of various sizes (You are a collector of boxes?!). Each box can contain one other box, which has size strictly smaller than itself. You have to put the boxes one inside of another in such a configuration that there are minimum number of boxes on the table.

Input

Input will start with the number of test cases, T (T ≤ 100). Following that will be the number of boxes, N (0 < N ≤ 100,000). The following N integers will denote the length of one side for each box, X (0 < X ≤ 2^30 ).

Output

For each test case, print one line of output, “Case Y: Z”. Where Y is the number of test case and Z is the minimum number of boxes on the table.

Solution - Timus Problem 1293. Eniya

1293. Eniya Time limit: 1.0 second Memory limit: 64 MB It’s restless now on the slips of the intergalactic port’s sixth dock of planet of Torn. No longer then in a month the reconstruction of the small ironclad corvette “Eniya” will be finished. And again this battle ship and its brave team would have to struggle for the control over plutonium mines of Sibelius. The work cannot be stopped even for a second, self-powered laser welders work round the clock. Joints of robots-repairers fuse because of this permanent work. Nevertheless, they can’t stop not for a single moment. Now in all this turmoil it is discovered that corvette’s thermopanels again need an urgent processing with thorium sulphide. It is known that the processing of the one square meter of the panel needs 1 nanogramm of sulphide. In general, it is needed to process  N  rectangular panels, which dimensions are  A  by  B  meters. It is necessary to calculate as fast as possible, how m...

Solution - Codeforces Problem 327B - Hungry Sequence

B. Hungry Sequence Iahub and Iahubina went to a date at a luxury restaurant. Everything went fine until paying for the food. Instead of money, the waiter wants Iahub to write a Hungry sequence consisting of  n  integers. A sequence  a 1 ,  a 2 , ...,  a n , consisting of  n  integers, is  Hungry  if and only if: Its elements are in increasing order. That is an inequality  a i  <  a j  holds for any two indices  i ,  j   ( i  <  j ) . For any two indices  i  and  j   ( i  <  j ) ,  a j  must  not  be divisible by  a i . Iahub is in trouble, so he asks you for help. Find a Hungry sequence with  n  elements. Input The input contains a single integer:  n  ( 1 ≤  n  ≤ 10 5 ). Output Output a line that contains  n  space-separated integers  a 1   a 2 , ...,  a n   (1 ≤  a i  ≤ 10 7 ) , representing a ...

Solution - Timus Problem 1409. Two Gangsters

1409. Two Gangsters Time limit: 1.0 second Memory limit: 64 MB Two gangsters Harry and Larry had a rest at countryside. They decided to spend some time shooting, so they put several beer cans (no more than 10) on a log. Harry started to shoot cans one after another from the leftmost to the right and Larry – from the rightmost to the left. At some moment it happened so that they shot one and the same can. Harry got indignant and claimed that Larry owed him a considerable sum of money because Larry deprived him of shooting some more cans. Larry became furious and told Harry that he owed even greater sum of money to Larry because of the same reason. They started to argufy but nobody remembered how many cans there were at the very beginning. And no one of them was going to search cans which was shot. Anyway, each of them remembered exactly how many cans he shot. Determine how many cans were not shot by Harry and how many cans were not shot by Larry. Input The only inp...
