## Task A-1.1.

Determine all three-digit numbers with the sum of digits 11, such that by swapping the units and hundreds digits, a number 594 greater is obtained.
## First solution.

We added 600 to the initial number and subtracted 6, so the units digit is 6 greater than the hundreds digit.

If the hundreds digit is at least 3, then the units digit is at least 9 and the sum of the digits is greater than 11.

If the hundreds digit is 1, then the units digit is 7, and the tens digit is 3, i.e., the number is 137. 1 point If the hundreds digit is 2, then the units digit is 8, and the tens digit is 1, i.e., the number is 218. 1 point
