/**问题描述：
8+
*
9+
* Given an integer, write an algorithm to convert it to hexadecimal.
10+
* For negative integer, two’s complement method is used.
11+
12+
Note:
13+
14+
All letters in hexadecimal (a-f) must be in lowercase.
15+
The hexadecimal string must not contain extra leading 0s. If the number is zero, it is represented by a single zero character '0'; otherwise, the first character in the hexadecimal string will not be the zero character.
16+
The given number is guaranteed to fit within the range of a 32-bit signed integer.
17+
You must not use any method provided by the library which converts/formats the number to hex directly.
18+
19+
Example 1:
20+
21+
Input:
22+
26
23+
24+
Output:
25+
"1a"
26+
Example 2:
27+
28+
Input:
29+
-1
30+
31+
Output:
32+
"ffffffff"
