For tnput:

Code: Select all

1 14
ONE       1500 2 2 0 3 1 5
ONE       0 1
ONE       0 2
ONE       0 3
ONE       0 4
ONE       0 5
ONE       1 1
ONE       1 2
ONE       1 3
ONE       1 4
ONE       1 5
ONE       2 1
ONE       2 2
ONE       2 3
ONE       2 4
Output should be:

Code: Select all

ONE[0, 1] = 1500
ONE[0, 2] = 1502
ONE[0, 3] = 1504
ONE[0, 4] = 1506
ONE[0, 5] = 1508
ONE[1, 1] = 1510
ONE[1, 2] = 1512
ONE[1, 3] = 1514
ONE[1, 4] = 1516
ONE[1, 5] = 1518
ONE[2, 1] = 1520
ONE[2, 2] = 1522
ONE[2, 3] = 1524
ONE[2, 4] = 1526

arh, brianfry713, Jan,

Thanks for the great test cases.

Turns out the judge's input does not have a case like so

Code: Select all

NAME                   
In other words, each line which defines an array contains the necessary information after the array name. The information is never not present. So, don't sweat that case.

I didn't necessarily find this problem "easy". Yes, it's straightforward once you understand what's being asked. However, the description took me months to unravel. Every time I'd read it, try to work things out by hand and hit a road block. I found this line especially tricky

Code: Select all

 C_d = C_(d+1)(U_(d+1) - L_(d+1) + 1) for 1 <= d < D
I kept thinking that there might be a typo and that it should read

Code: Select all

 C_d = C_(d+1)(U_(d+1) - L_(d+1) + 1) for 1 <= d <= D
instead. However, this isn't the case. The description is accurate as is. After a lot of trying, I finally understood what the problem's stating.

So, in summary, if you're finding it challenging, you're not alone.

This works fine for all of the sample inputs I can find.
It is throwing a runtime exception when I send it to the judge, though.
Anyone have any clue as to why?

Code: Select all

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;
import java.util.StringTokenizer;

class Main {

	void solve() throws IOException {
		InputReader reader = new InputReader( System.in );
		int numArrays = reader.nextInt();
		int numArefs = reader.nextInt();
		Map<String, ArrayRef> nameToRef = new HashMap<String, ArrayRef>();

		for ( int i = 0; i < numArrays; ++i ) {
			ArrayRef ref = new ArrayRef( reader.nextName() );
			nameToRef.put( ref.name, ref );

			ref.setBaseAddress( reader.nextInt() );
			ref.setSizeOfEls( reader.nextInt() );
			ref.setDimensions( reader.nextInt() );

			for ( int j = 0; j < ref.dimensions; ++j ) {
				ref.lowerBounds[j] = reader.nextInt();
				ref.upperBounds[j] = reader.nextInt();
			}
		}

		for ( int i = 0; i < numArefs; ++i ) {
			String name = reader.nextName();
			ArrayRef ref = nameToRef.get( name );

			if ( ref == null ) {
				reader.clear();
				continue;
			}

			int[] idx = new int[ ref.getDimensions() ];
			for ( int k = 0; k < idx.length; ++k ) {
				idx[k] = reader.nextInt();

Re: 394 - OMG what about integer overflow?

Post by javpaw » Sun Jan 31, 2016 4:14 pm

Hi.

Why the constants (C) in this problem can be stored as integers (int in c++) when for a lot of cases this type is not enough?

I really don't get it, please help me, where in the problem is specified that overflow of int is allowed?

think for example in this entry:

1 1
A 0 1 10 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000 1 1000000
A 1000000 1000000 1000000 1000000 1000000 1000000 1000000 1000000 1000000 1000000

C10 = 1
C9 = 1*1M
C8 = 1M*1M
C7 = 1M*1M*1M
....

C1 in this case should be a really big number (10^6)^9 = 10^54, between 1^179 and 2^180

There are no more than 1000 arrays in the test input.
Number of arrays is not more than 5.
