developerphp5 Posted November 9, 2011 Share Posted November 9, 2011 I need help with regexp to find the number of occurrencies of the string "join the nmi team" for each line.

developerphp5 Posted November 9, 2011 Author Share Posted November 9, 2011 this is the hint i got this is the hint The word we want to find is S = "join the nmi team", in a long string T. In fact the solution is not very different when we want to find any S. It is actually illustrative to picture the cases for short words. In case S is just a single character, you just need to count how many times this character appears in T. If S = "xy" is a string of length 2, instead of brute force all the possible positions, one can do it in linear time, start from left to the right. For each occurrence of 'y', one needs to know how many 'x's appeared before that 'y'. The general solution follows this pattern. Let us again use S = "join the nmi team" as an example. So, let us define, for each position i in T, T(i) to be the string consists of the first i characters of T. And write Dp[i,1]: How many times we can find "j" in T(i)? Dp[i,2]: How many times we can find "jo" in T(i)? Dp[i,3]: How many times we can find "joi" in T(i)? Dp[i,4]: How many times we can find "join" in T(i)? ... Dp[i,16]: How many times we can find "join the nmi tea" in T(i)? Dp[i,17]: How many times we can find "join the nmi team" in T(i)? Assume Dp[i,j] is computed for each j, let us see how easy we can compute, say, Dp[i+1,4]: If the (i+1)-th character of T is not 'n', then Dp[i+1,4] = Dp[i,4]. If the (i+1)-th character of T is 'n', then we can include all the "join"s found in T(i), as well as those "join"s ends exactly on the (i+1)-th character, so Dp[i+1,4] = Dp[i,4] + Dp[i,3]. Finally, let n be the length of the text T, Dp[n,17] will be our answer.

xyph Posted November 9, 2011 Share Posted November 9, 2011 Have you attempted this? Could you show us the code you're using to 'explode' the string into individual lines? That hint makes my brain hurt. I understand it, but I don't see the relevance, or how it comes remotely close to clarifying the solution.

developerphp5 Posted November 9, 2011 Author Share Posted November 9, 2011 its a text document so i am getting data from text docuemnt and then processing if (is_uploaded_file($_FILES['userfile']['tmp_name'])) { $filePointer = fopen($_FILES['userfile']['tmp_name'], "rb"); if ($filePointer!=false){ while (($get_line = fgets($filePointer, 4096))) { $get_line_array[] = $get_line; } $i = 1; // $string_match = preg_grep('/\join the nmi team/g', $get_line_array); // print_r( $string_match ); foreach ($get_line_array as $value) { $needle = "join the nmi team"; // echo "Line" . $i . ": " . substr_count($value,"join the nmi team",0,17) . "<br>" ; //$value = str_replace(' ', '', $value); //echo $value . "<br>" . "<br>" ;//contains that wall of text you decided to paste here. //$search = preg_match_all("/jointhenmiteam/", $value, $found); //print_r(count($found)); // [^\s]*jo(?!werty)[^\s]* // $regexp = "/^join/ /the/ /nmi/ /team/i" ; // $string_match = preg_match("/join the nmi team/", $value ,$matches); // print_r($matches); $i++; } fclose($filePointer); } } Quote Link to comment https://forums.phpfreaks.com/topic/250803-help-with-regexp/#findComment-1286819 Share on other sites More sharing options...
xyph Posted November 9, 2011 Share Posted November 9, 2011 I see that you can copy and paste code. Do you understand what you've copied and pasted? I was also asking myself how long it would take you to realize 'join the nmi team' never actually shows up in the giant mass of text you gave us.

xyph Posted November 9, 2011 Share Posted November 9, 2011 The string 'join the nmi team' doesn't show up once in that example. You're searching for something that doesn't exist. You're asking for help to find something that isn't there.

developerphp5 Posted November 9, 2011 Author Share Posted November 9, 2011 this is the hint i got but i didnt know like where to start The word we want to find is S = "join the nmi team", in a long string T. In fact the solution is not very different when we want to find any S. It is actually illustrative to picture the cases for short words. In case S is just a single character, you just need to count how many times this character appears in T. If S = "xy" is a string of length 2, instead of brute force all the possible positions, one can do it in linear time, start from left to the right. For each occurrence of 'y', one needs to know how many 'x's appeared before that 'y'. The general solution follows this pattern. Let us again use S = "join the nmi team" as an example. So, let us define, for each position i in T, T(i) to be the string consists of the first i characters of T. And write Dp[i,1]: How many times we can find "j" in T(i)? Dp[i,2]: How many times we can find "jo" in T(i)? Dp[i,3]: How many times we can find "joi" in T(i)? Dp[i,4]: How many times we can find "join" in T(i)? ... Dp[i,16]: How many times we can find "join the nmi tea" in T(i)? Dp[i,17]: How many times we can find "join the nmi team" in T(i)? Assume Dp[i,j] is computed for each j, let us see how easy we can compute, say, Dp[i+1,4]: If the (i+1)-th character of T is not 'n', then Dp[i+1,4] = Dp[i,4]. If the (i+1)-th character of T is 'n', then we can include all the "join"s found in T(i), as well as those "join"s ends exactly on the (i+1)-th character, so Dp[i+1,4] = Dp[i,4] + Dp[i,3]. Finally, let n be the length of the text T, Dp[n,17] will be our answer.

seanc722 Posted November 9, 2011 Share Posted November 9, 2011 Curious.. The lines you posted that you are suppose to search, are they taken from an example or did you just mash buttons to create it?
