No? Oh, you must do this when you want to become a “Big Cattle”. Now you will find that this problem is so familiar: The greatest common divisor GCD (a, b) of two positive integers a and b, sometimes written (a, b), is the largest divisor common to a and b. For example, ...
lines follow, each containing two integersxandy(1≤x,y≤n,x≠y)denoting an edge connecting vertexxwith vertexy . It is guaranteed that these edges form a tree. Output If there is no pair of verticesx,y such thatg(x,y)>1, print0. Otherwise print the maximum value ofdist(x,y) ...
