Each of the next B lines contains one integer between 2 and 60 (inclusive) which denotes the age of one bachelor in the community. Each of the next S lines contains one integer between 2 and 60 (inclusive...

Second input (exactly 6, 7, 8, 9, 12, 13, 15, 17 test cases) on uDebug named by "Online Uva judge" is not correct. Because creature's names are listed in one line. But according to problem's description they should be on C lines, where C is number of creatures. Follow C lines with the names of the c...

Although this is not clearly mentioned in the problem statement, the following is probably true: If there exists one word in the dictionary there can exist several #'s in the input; otherwise, if there exist several words in the dictionary, there exists no more than one # in the judge's input. Why ...

### Re: 10447 - Sum-up the Primes (II)

Solved with dp. My previous dp approaches gave me TLE.

Memory : 244*800*12, where 244 = 61 * 4 (4 is maximum frequency).

Time___: 244*800*12, for each block of input.

Now for Jujuedv's test case uDebug gives correct answer 6. Some information that may be relevant for anyone working on this problem: my code passed even though it returned different results for the test input of Morass in uDebug. Concretely the following lines differed: Line 494 -> uDebug 53, Mine 5...

### Re: 884 - Factorial Factors

My code accepted in 0.020. My sieve is similar to yours, but it's not bitwise. You can optimize second step. I precalculated all the results without factorization. I calculate it in O(1000000) with only one loop. I used array cnt[1000001], instead of variable cnt. For each N from 2 to 1000000 store ...

### Re: 10102 getting Wrong Answer , please help me to solve it

If you assume that square field can have size 1000x1000 , then you should also assume that number of cells with color 1 or color 3 can be at most 999999 . But your arrays xo, yo, xt, yt have size only 1000 . You should get RE in this case, but not always. Sometimes you get WA. I checked that size of...

### Re: 10102 getting Wrong Answer , please help me to solve it

You initialized variable
Also you should print a newline after the answer.

**e**by value 1, so your code always prints blank line before printing the answer.Code: Select all

```
int xo[1000], yo[1000], xt[1000], yt[1000], maxi, N,e=1;
..
if (e)cout << endl;
cout << maxi;
e = 1;
