... tell you, so long as the program gives the same answers. It might allocate some temporary Objects on the stack. It may optimize some variables or method calls totally out of existence replacing them with constants. It might version methods or loops, i.e. compile two versions of a meth...

...er("") to set the delimiter to an empty string. This will cause next() to tokenize into strings that are exactly one character long. So then you can repeatedly call next().charAt(0) to iterate the characters. You can then set the delimiter to its original value and resume scanning in the normal w...

...E has spaces unless they are already escaped. You'll get one line with two tokens each and then [UP] for every two space-separated tokens in your variable and then a single line at the end with your line text minus the total length of your input string. So be careful, since this could lead to intere...

...ed in will not be modified. Once you create a string "foo", some memory is allocated to store the value "foo". This memory will not be altered. If you modify the string with, say, substr(1), a new string is created and a different part of memory is allocated which will store "oo". Now you have two s...

...in multithreaded applications, or is there a significant risk that smaller allocations in other threads fail because of it? … presumably only if your arrays were just small enough to be allocated, but left nothing for anyone else. – PJTraill Jun 11 '15 at 14:...

...oduce this is beyond the scope of this answer but the TL;DR is that secret_token.rb conflates configuration and code as well as being a security risk since the token is checked into source control history and the only system that needs to know the production secret token is the production infrastruc...

... avoided". As BrodieG mentioned in the comments: it is much better to pre-allocate a vector of the desired length, then set the element values in the loop. Here are several ways to append values to a vector. All of them are discouraged. Appending to a vector in a loop # one way for (i in 1:le...

... instance, if a hash function has a range R(h) = 0...100, then you need to allocate an array of 100 (pointers-to) elements, even if you are just hashing 20 elements. If you were to use a binary search tree to store the same information, you would only allocate as much space as you needed, as well as...
