Why is my implementation of binary search very inefficient?

python,recursion,binary-search

if word in wordlist[len(wordlist)/2:] will make Python search through half of your wordlist, which is kinda defeating the purpose of writing a binary search in the first place. Also, you are not splitting the list in half correctly. The strategy for binary search is to cut the search space in...

javascript,arrays,performance,loops

This is not so much a good practice as a small performance optimization. In very large arrays it will yield a significant performance improvement. The reason for doing this is that it "caches" the length value of the array, NodeList, etc., so that in your loop's exit condition you don't...

Allowed memory size of 268435456 bytes exhausted with array

MS SQL Store Procedure to Merge Multiple Rows into Single Row based on Variable Table and Column Names

sql,sql-server,sql-server-2008,stored-procedures

I'm probably missing something, but the basic idea to solve the problem is to use meta-programming, like a dynamic pivot. In this particular case there is another layer to make the solution more difficult: the result need to be in different execution instead of beeing grouped. The backbone for a...

OpenRDF Sesame: how to handle locking?

concurrency,transactions,sparql,sesame,openrdf

NSMutableArray is empty when reaches numberOfRowsInSection and cellForRowAtIndexPath

ios,objective-c,arrays,tableview
