instaceof只可以用来判断数组和对象,不能判断string和boolean类型 下面为封装方法进行改进 varo ={'name':'lee'};vara = ['reg','blue'];vargetDataType =function(o){if(oinstanceofArray){return'Array'}elseif( oinstanceofObject ){return'Object'; }else{return'param is no object type'; } }; ...
Given two strings:s1ands2with the same size, check if some permutation of strings1can break some permutation of strings2or vice-versa (in other wordss2can breaks1). A stringxcan break stringy(both of sizen) ifx[i] >= y[i](in alphabetical order) for allibetween0andn-1. Example 1: ...
