Accept two positive integers a and b as input. Print the sum of all integers in
the range [1000, 2000], endpoints inclusive, that are divisible by both a and
b. If you find no number satisfying this condition in the given range, then print
0.
Input
Two lines: the integer a on the first line and the integer b on the second line.
Output
A single integer: the sum described above, or 0 if no number in the range is
divisible by both.
Write a complete program: read the input with input() and print the result with print().
