解法1:字符串反转 解法2:数学运算(求余)转换 解法3:递归解法 这个题其实是 LeetCode 9 的基础题。可见,LeetCode 的题目编排就是乱来。 不过呢,相对 LeetCode 9,此题存在一些小的细节必须考虑周全。 题目要求看上去很简单,就是把一个整数从右到左翻过来。比如5,翻过来还是5;123,翻过来就是 321;-124,反过...
The input is assumed to be a 32-bit signed integer. Your function shouldreturn 0 when the reversed integer overflows. 解题思路: python里面int最大数值0x7FFFFFFF,在考虑溢出的时候需要和这个值进行比较。 取模运算可以得到数字的最后一位,/运算会得到移走最后一个数字之外的数字,以此循环 代码如下: #!
7. Reverse Integer Reverse digits of an integer. Example1:x = 123, return 321 Example2:x = -123, return -321 click to show spoilers. Note: The input is assumed to be a 32-bit signed integer. Your function shouldreturn 0 when the reversed integer overflows. My Solution 参考答案Python2...
Reverse digits of an integer. Example1: x = 123, return 321 Example2: x = -123, return -321 题目提示: Have you thought about this? Here are some good questions to ask before coding. Bonus points for you if you have already thought through this! If the integer’s last digit is 0,...
int(x), to convert x into an integer value long(x), to convert x into a long integer value float(x), to convert x into a floating-point number complex(x), to convert x into a complex number where the imaginary part stays 0 and x becomes the real part complex(x,y), to convert...

Given a string and an integer k, you need to reverse the first k characters for every 2k characters counting from the start of the string. If there are less than k characters left, reverse all of them. If there are less than 2k but greater than or equal to k characters, then reverse...
尝试着用python递归实现fib,发现直接超出了递归的最大限制次数: # fib递归的算法会严重超时 deffib(a1): v1=0 v3=0 if(a1>1): v1=fib(a1-1) v3=v1+fib(a1-2) else: v3=a1 returnv3 提示max recursion depth exceeded 典型的斐波拉契数列,wiki 一下就知道,有多种算法实现: ...
