Indeed, that's what I got for the sample input, but my output is different from the sample output:

Get wrong answer, really don't know where the code fails for which special cases? :oops: /* 1590 - IP Networks Author: Peter Lee Contact: leestime.com <at> gmail.com Algorithm: bitwise Notes: */ #include <cstdio> #include <iostream> #include <vector> #include <bitset> #define N 32 using namespace st...

If you guys think this problem from a different perspective, it's super easy: /* 11150 - Cola Author: Peter Lee Contact: leestime.com <at> gmail.com Algorithm: ad-hoc Notes: 1.

This is an invalid input, because

Each of the two given integers is not less than 1, and the length of their sum does not exceed M.

OK. I switched to use the native C function strstr, and it got accepted, which does NOT make too much sense!

There's Knuth-Morris-Pratt algorithm. Find using it position of the first occurrence of s in string s*s. I used the same strategy, but still got TLE, I believe my algorithm is O(n): inline int GetLargestN(const char* cs) { string s(cs); string ss(s, 1); ss += s; ss += s[0]; int len = s.length(); in...

NO. they should NOT be counted multiple times in the output. because the problem description clearly states

number of DIFFERENT words

In the problem description, it states very clearly: For each puzzle line in the input, a single line of output should be produced, containing the number of DIFFERENT words in the dictionary that can be formed using the letters in the puzzle line. My code runs with the following input: ant bee cat do...

Do you consider the case that same word may appear more than once in the dictionary ? You mean the dictionary can contain the same word twice. For example : cat cat dog lion # c a t # will output 2. I applied the method that .. mentioned and got AC.. but still can't figure out why the original was ...

I am having the same problem. It's always submission error.

I also tried to submit a different problem and then came back to submit 755, but I still got the same problem.

Please take a look at it.

0 should not be in the test data; The maximum input: 4786 (f(4786) has 1000 digits, while f(4787) has 1001 digits) Test Input: 4786 3 100 20 1 2 3 4 4781 43 44 45 46 Test Output 73343433004315267454132492084714809412958860393838856895917990126606213167793958237053069359544403744909833164405109382186...

And should I also take the inbalance parenthesis into account, if it's required, this problem would be so complicated. thanks everyone, can someone reply?

I'm sorry. I forgot to change this line: To: Everytime I need to make this change before submission.

However, I'm now using this:

I think the concept is fairly simple. Convert infix notation to postfix notation. Then using the postfix notation, parse it and anytime there's supposed to be an operator, recusively plug in either +, - and *.
