引言 前一阵做了一个有理数四则混合运算的程序(详见:用C++实现的有理数(分数)四则混合运算计算器),以分数形式呈现运算结果.这次添加以循环小数形式呈现运算结果的功能.例如: Please input a rational expression to calculate its value or input q to quit: 67+34*(23-78/(54*5))-2*(5/37-6.5789) = 67 + 34 * ( 23 - 78 / ( 270 ))-2*(5/37-6.5789…

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. Example 1: Input: numerator = 1, denominator = 2 Output…
It is easy to see that for every fraction in the form (k > 0), we can always find two positive integers x and y,x ≥ y, such that: . Now our question is: can you write a program that counts how many such pairs of x and y there are for any givenk? Inp…
