Given an integer, return its base 7 string representation. Example 1: Input: 100 Output: "202" Example 2: Input: -7 Output: "-10" Note: The input will be in range of [-1e7, 1e7]. 给一个整数,返回它的七进制数. 解法1: 迭代 解法2: 递归 Java: public class Solu…
504. Base 7 Given an integer, return its base 7 string representation. Example 1: Input: 100 Output: "202" Example 2: Input: -7 Output: "-10" Note: The input will be in range of [-1e7, 1e7]. 思路:辗转相除法.…
Given an integer, return its base 7 string representation. Example 1: Input: 100 Output: "202" Example 2: Input: -7 Output: "-10" Note: The input will be in range of [-1e7, 1e7]. 这道题给了我们一个数,让我们转为七进制的数,而且这个可正可负.那么我们想如果给一个十进制的100,怎么转为七进制…
Given an integer, return its base 7 string representation. Example 1: Input: 100 Output: "202" Example 2: Input: -7 Output: "-10" Note: The input will be in range of [-1e7, 1e7]. 不停除以7, 然后把余数放到ans里面, 最后reverse ans加上符号即可. Code class Sol…
题目: Given an integer, return its base 7 string representation. Example 1: Input: 100 Output: "202" Example 2: Input: -7 Output: "-10" Note: The input will be in range of [-1e7, 1e7]. 分析: 给定一个7进制数,求十进制表示,注意返回的是字符串. 进制转换没什么好说的,注意这道题测试用例是…
