// Poj 1131 Al fractions decimal conversion between any hexadecimal notation// You must convert an octal decimal point to a decimal point,// The number of decimal places after conversion is three times the number of decimal places in the first eight decimal places before conversion, and no meaningless zero at the end is output (that is, the post zero ).// The method I used is to multiply 10 and then get an integer for 8 (now we assume that the decimal

Topic:When he was in elementary school, Xiaoming often invented his own new algorithm. Once, the teacher's topic is:1/4 times 8/5 Xiao Ming incredibly put the molecules together, the denominator stitching together, the answer is: 18/45The teacher was just trying to criticize him, and then he thought, the answer happened. For the numerator and denominator are all one-digit numbers in the 1~9, what other formulas can be computed like this?Please write down the number of all the different formulas

Fractions again?! It's easy-to-see-every fraction in the form 1/k (k > 0), we can always find a positive integers x and y, X >= y, such that:.Now we question Is:can you write a program this counts how many such pairs of x and Y there is for any given k? Input input contains no more than to lines, each giving a value of K (0 Output for each k, output the number of corresponding (x, y) pairs, followed by a sorted list of the values of x and Y, as Shown
