### Re: 11475 - Extend to Palindromes

@baodog: Your code prints an extra unprintable character at the end of each line on my machine. But it looks otherwise ok. @hamedv: I'm curious about the O(n^2) DP you mentioned. The simple brute force way of solving this problem is also O(n^2). Could you please post an outline of your idea? I mean...

### Re: 11472 - Beautiful Numbers

I keep track of used numbers so far a the first dimension of an array. The other 2 dimensions are length and the last digit. For example 5 (101) means that I used numbers (0 and 2). When I find answers for each length I iterate through (111) values for each length and every digit to the left of the...

### Re: 11472 - Beautiful Numbers

if (LASTDIGIT = 0 ans DIGITS = 1) ----------- mydpfunction(BASE, DIGITS, LASTDIGIT) = 0; IMHO the problem may be here. Don't assume, that the number 0 can't be used in DIGITS > 1. Since the number 10 is produced by adding 1 to zero. Once you have found the answer of a particular length. You can ite...

### Re: 11475 - Extend to Palindromes

Yes, i don't know too

There were problems like this an i solved them using DP, because the input size was less than 1000 but in this problem it's so huge.

Hi

I don't know why my code produces 352 triples. It also produced 352 triples after I changed my code as you said in previous posts. Please tell me which triples am i missing?

Here is my code:
