Given a sorted array of integers, find the starting and ending position of a given target value.
Your algorithm's runtime complexity must be in the order of O(log
n).
If the target is not found in...

Perl中著名的Schwartzian转换,其产生背景主要涉及到排序问题:
比如说,根据文件名以字母顺序排序,代码如下:
use strict;
use warnings;
my @files = glob "*.xml"; #perl中文件操作符glob提供相当于shell中的通配符的功能
my @sorted_files = sort @files; #sort(),排序,默认是字母顺序排序
比如说,根据文件名长度排序,其代码如下:
use strict;
use warni...

对翻过一次的排序数组二分查找,要利用好已排序这个条件
class Solution {
public:
int search(int A[], int n, int target) {
int left = 0, right = n-1;
while(left <= right){
int mid = (left+right)/2...
