2008年8月29日 · In short, a tail recursion has the recursive call as the last statement in the function so that it doesn't have to wait for the recursive call. So this is a tail recursion i.e. N(x - …

Tail-recursion is a form of recursion in which the recursive calls are the last instructions in the function (that's where the tail part comes from). Moreover, the recursive call must not be …

2008年11月22日 · And on tail recursion: Tail recursion happens if a function, as its last operation, returns the result of calling itself. Tail recursion is easier to deal with because rather than …

2010年4月22日 · Tail recursion (and tail calling in general) requires clearing the caller's stack frame before executing the tail call. To the programmer, tail recursion is similar to a loop, with …

Strange. I just tested gcc 4.2.3 (x86, Slackware 12.1) and gcc 4.6.2 (AMD64, Debian wheezy) and with -O1 there is no inlining and no tail-recursion optimization. You have to use -O2 for that …

2010年4月20日 · Tail recursion elimination is the same thing, but with the added constraint that the function is calling itself. Basically, if the very last thing a function A does is return …

2013年3月20日 · Tail recursion is a simple recursive function, where recurrence is done at the end of the function, thus no code is done in ascendence, which helps most compilers of high …

Tail recursion is immitating loops with no stack [or any other data structure], i.e. O(1) additional space. AFAIK, the problem at hand, of tree/graph traversal [assume no parent field in each …

2013年3月21日 · Very nice answer! I think the Fibonacci "double recursion" can be turned into pure tail-recursion because this particular problem can be solved in O(1)-space using an …

2021年12月31日 · Tail-recursion elimination is a special case of tail-call elimination, not a special case of some form of recursion optimization. Normally , when you call a subroutine, you have …
