the definition of problem is: given 2 strings, find longest common substring. return length of it. i solving problem , think solved o(m*n) time complexity. don't know why when solution, it's talking optimal solution being dynamic programming - http://www.geeksforgeeks.org/longest-common-substring/ here's solution, can test here: http://www.lintcode.com/en/problem/longest-common-substring/ int longestcommonsubstring(string &a, string &b) { int ans = 0; (int i=0; i<a.length(); i++) { int counter = 0; int k = i; (int j=0; j<b.length() && k <a.length(); j++) { if (a[k]!=b[j]) { counter = 0; k = i; } else { k++; counter++; ans = max(ans, counter); } } } return ans; } my idea simple, start first position of string , see what's longest substring can mat

i'm using function call clone() clone (fun, (char*)stack + 0x500000, sigchld | clone_files | clone_fs, arg); where fun function: int fun(void*), stack = malloc (0x500000), , arg of type void*. i'm wondering other possible causes invalid argument perror. i have checked stack not null. man clone: child_stack argument specifies location of stack used child process. since child , calling process may share mem‐ ory, not possible child process execute in same stack calling process. calling process must therefore set memory space child stack , pass pointer space clone(). stacks grow downward on processors run linux (except hp pa processors), child_stack points topmost address of memory space set child stack.

is possible merge 3 or more dom objects in jquery? found solution here in stackoverflow, merging 2 objects: merging jquery objects my example: var input1 = $('.input-1'), input2 = $('#parent-div input'), input3 = $('.input-3'), input4 = $('.input-4'), input5 = $('.input-5') merge([input1, input2, input3, input4]).val('my custom input text'); in case have several inputs want merge few of them. can use $.add() in following way: $(document).ready(function(){ var input1 = $('.input-1'); var input2 = $('#parent-div input'); var input3 = $('.input-3'); var input4 = $('.input-4'); var input5 = $('.input-5'); var collection = $( input1 ); // capture new collection collection = collection.add( input2).add(input3).add(input4); collection.val('my custom input text'); }); <script src="https://ajax.googleapis.co

i'm trying find solution problem i'm facing asp.net application (c# / mysql backend). the application uses webforms in multi step wizard insert data sql database, various steps javascript driven no 'submit' done until 'last' step. in circumstances anyway if user click browser 'back' button after 'last' step form resubmitted , sql insert triggered again creating dupes of original record. i tought use ajax based mechanism track steps of form until wizard reach 'last' step. after trough same ajax function prevent resubmit of form preventing dupes. i don't want use javascript tricks disable button obvious reasons. the main problem of solution don't , quite difficult implement since wizards on application form quite articulated , may cause problem. is there 'best practice' prevent such issues without building complex infrastructures? i'm not posting code because think misleading , unnecessary. best regards
