Bill's Age and Alice's Age (Posted on 2025-01-26) Difficulty: 3 of 5
If Bill’s age in years is appended to Alice’s age, the resultant four digit integer is a perfect square.

The same thing will be true thirteen years from now. What are Bill’s and Alice’s ages?

If Bill’s age in years is appended to Alice’s age, my interpretation is that Alice's age is listed first followed by Bill's.

So Alice is 19 and Bill is 36 years old.

---------
squares = [n**2 for n in range(32,106)]

for s in squares:
    later13 = s + 1313
    if later13 in squares:
        print(s, later13)
