GRAYCODE.C(转载)(2006-06-12 09:07:00)
摘要：/* ------------------------------------------------------ *//* PROGRAM Subset Generation by Gray Code : *//* This program generates all possible subsets of a n *//* elements set with Gray Code. Simply speaking, the Gray*//* code of n bits is a sequence of n-bit strings such that*//* any two consecutive two bit strings have exactly one *//* position in difference. For example, for n = 3, the *//* gray code generated is the sequence 000,001,010,011, *//* 010,110,111,101 and 100. Therefore each item of this *//* sequence corresponds one subset as in the direct method*//* ......
