Symmetric Difference Create a function that takes two or more arrays and returns an array of the symmetric difference (△ or ⊕) of the provided arrays. Given two sets (for example set A = {1, 2, 3} and set B = {2, 3, 4}), the mathematical term "symmet…
题目链接 集合操作 附上代码: M = int(input()) m = set(map(int, raw_input().strip().split())) N = int(input()) n = set(map(int, raw_input().strip().split())) tmp = sorted(m.union(n).difference(m.intersection(n))) for i in xrange(len(tmp)): print tmp[i]…
function sym(args) { //return args; var arr = []; for(var i = 0; i < arguments.length; i++){ arr.push(arguments[i]); } var temp = arr.reduce(function(prev,cur,index,array){ var a = prev.filter(function(item){ return cur.indexOf(item) < 0; }); var b…
python的官网里对集合的描述是: Python also includes a data type for sets. A set is an unordered collection with no duplicate elements. Basic uses include membership testing and eliminating duplicate entries. Set objects also support mathematical operations like…
基本数据类型补充: set 是一个无序且不重复的元素集合 class set(object): """ set() -> new empty set object set(iterable) -> new set object Build an unordered collection of unique elements. """ def add(self, *args, **kwargs): # real signature un…
