Yesterday i saw in a post a guy said that built in Stack/Queue are 5x slower than a normally coded Stack/queue !
Is it true ?
If true then why Microsoft (C#.NET,VB.NET) or Oracle (JAVA) is giving such ADT ?
Which one you prefer ? Writing your own or using the built in ?
[I think most of the people prefer the built in as the code have been tested many times and is very very optimized]
