Problem G
Solidus Fraction
A fraction written with a solidus (/) can be written “inline”. However, a fraction may also be written with a horizontal line, known as a vinculum. When a vinculum is used, the numerator is written above and the denominator is written below.
Write a program to convert a vinculum fraction to a solidus fraction.
Input
The first line contains the numerator ($n$) and optional whitespace allowing the numerator to be centered or right-aligned. The second line contains only the vinculum, which consists of one or more dashes (-). The third line contains the denominator ($d$) and optional whitespace allowing the denominator to be centered or right-aligned. ($-10^{18} \leq d,n \leq 10^{18}, d \neq 0$)
Output
Write one line of output containing the reduced fraction, only use a solidus if necessary.
