给定两个整数,分别表示分数的分子 numerator 和分母 denominator,以字符串形式返回小数. 如果小数部分为循环小数,则将循环的部分括在括号内. 示例 1: 输入: numerator = 1, denominator = 2 输出: "0.5" 示例 2: 输入: numerator = 2, denominator = 1 输出: "2" 示例 3: 输入: numerator = 2, denominator = 3 输出: "0.(…

给定两个整数,分别表示分数的分子和分母,返回字符串格式的小数.如果小数部分为循环小数,则将重复部分括在括号内.例如,    给出 分子 = 1, 分母 = 2,返回 "0.5".    给出 分子 = 2, 分母 = 1,返回 "2".    给出 分子 = 2, 分母 = 3,返回 "0.(6)". 详见:https://leetcode.com/problems/fraction-to-recurring-decimal/descriptio…

Given two integers representing the numerator and denominator of a fraction, return the fraction in string format. If the fractional part is repeating, enclose the repeating part in parentheses. For example, Given numerator = 1, denominator = 2, retu…

思路: 模拟. 实现: class Solution { public: string fractionToDecimal(int numerator, int denominator) { long long a = numerator, b = denominator; string ans = ""; ) ans += '-'; a = abs(a); b = abs(b); ans += to_string(a / b); a %= b; if (!a) return ans;…

分数转小数,要求输出循环小数 如2 3 输出0.(6) 弗洛伊德判环的原理是在一个圈里,如果一个人的速度是另一个人的两倍,那个人就能追上另一个人.代码中one就是速度1的人,而two就是速度为2的人. Fraction to Recurring Decimal可以使用弗洛伊德判环,不同的是要找到循环出现的起始点,因此会比单单判断是否循环出现的题要难一点,代码要长一点,但是它比是用map的实现会更快. 要做出这道题有几个注意点: 1)对于整数的求余和整除运算要注意,特别负数的求余运算, 可以参考…
