Many times we need to determine the presence of duplicate or repeated elements in a javascript array such as when applying a duplicate validation over a field on a page. There are many ways to check for elements of same value in a javascript array and th
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...

There is only one duplicate number innums, returnthis duplicate number. Follow-ups: How can we prove that at least one duplicate number must exist innums? Can you solve the problem without modifying the arraynums? Can you solve the problem using only constant,O(1)extra space?

There is only one duplicate number in the array, but it could be repeated more than once. 思路: 不能修改数组所以不能排序,不能用额外的空间所以不能用HashMap,考虑鸽巢原理。数的范围在1~n之间,有n+1个数 猜测重复数为n/2,计算 数组中大于n/2的次数count,如果重复的数在n/2~n之间的话,count应...
