You must not modify the array (assume the array is read only). You must use only constant, O(1) extra space. Your runtime complexity should be less thanO(n2). There is only one duplicate number in the array, but it could be repeated more than once 非常好的题目,开始是用二分做的,比...
WithES6, we have a javascriptSetobject which stores only unique elements. ASetobject can be created with array values by directly supplying the array to its constructor. If the array has duplicate values, then they will be removed by theSet. This means that theSetwill only contain unique array...
