405. Convert a Number to Hexadecimal
来源:互联网 发布:网店美工工作职责 编辑:程序博客网 时间:2024/05/18 03:10
Given an integer, write an algorithm to convert it to hexadecimal. For negative integer, two’s complement method is used.
Note:
- All letters in hexadecimal (
a-f
) must be in lowercase. - The hexadecimal string must not contain extra leading
0
s. 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. - The given number is guaranteed to fit within the range of a 32-bit signed integer.
- You must not use any method provided by the library which converts/formats the number to hex directly.

code:
class Solution(object):
def toHex(self, num):
"""
:type num: int
:rtype: str
"""
if num == 0:
return "0"
elif num < 0:
num += 2 ** 32
dic={0:0,1:1,2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:'a',11:'b',12:'c',13:'d',14:'e',15:'f'}
res=[]
while num!=0:
res.append(str(dic[num%16]))
num=num/16
return "".join(res[::-1])
def toHex(self, num):
"""
:type num: int
:rtype: str
"""
if num == 0:
return "0"
elif num < 0:
num += 2 ** 32
dic={0:0,1:1,2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:'a',11:'b',12:'c',13:'d',14:'e',15:'f'}
res=[]
while num!=0:
res.append(str(dic[num%16]))
num=num/16
return "".join(res[::-1])
