#45 Problem

** Thoughts ** Since the solution range of mod2019 is 0 to 2018, it is not necessary to calculate more than 2018. Since 0 is the minimum value, the calculation will stop when it reaches 0.

l, r = map(int,input().split())

ans = 2019
flag = False
for i in range(l,r+1):
    for j in range(i+1,r+1):
        ans = min(ans,(i*j)%2019)
        #print(i,j)
        if ans == 0:
            flag = True
            break
    if flag:
        break
print(ans)

Summary

I received the Master of Integer, so I will proceed. see you
