Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. 解题思路: JAVA实现如下: public void rotate(int[] nums, int k) { k%=nums.length; k=nums.length-k; int[] nums2=ne…

String 类: 1. 对于String对象的相等性判断来说,请使用equals()方法,而不是==.String的equals()是判断当前字符串与传进来的字符串的内容是否一致. 2. String是常量,其对象一旦创建完毕就无法改变.当使用+拼接字符串时,会生成新的String对象,而不是向原有的String对象追加内容. 3. String Pool (字符串池) 在方法区中. 4. String s = “aaa”;(采用字面值方式赋值) 1). 查找 String Pool 中是否存…

题目描述: Given an array of n integers where n > 1, nums, return an array output such that output[i] is equal to the product of all the elements of nums except nums[i]. Solve it without division and in O(n). For example, given [1,2,3,4], return [24,12,8,…

题目描述: Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note:You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements…
