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…

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…

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…

原题地址 计算循环小数 先把负数转化成正数,然后计算,最后添加符号 当被除数重复出现的时候,说明开始循环了,所以用一个map保存所有遇到的被除数 需要考虑溢出问题,这也是本题最恶心的地方,看看通过率吧,比Hard难度的题还低. 最残暴的做法是直接转成64位长整型,比如下面的代码.好处是代码简洁了许多,不过这是投机取巧,因为如果题目把参数换成两个64为长整型,这个方法就不行了. 如果不用64长整型,就用32位普通整型怎么办? 由于我们要把除数和被除数转化成正数,所以当其中任意一个数等于INT_MI…
