# Distinct Sum

**Number Theory**Level 3

Let the 10 letters \( A\) to \(J\) represent each of the digits \(0\) to \(9\) (not necessarily in order.

What is the minimum value of \( \overline{A} + \overline{BC} + \overline{DEF} + \overline{GHIJ} \)?

\( \overline{ABC} \) refers to reading the number in decimal base. \(\overline{ABC} = 100A + 10B + C \), and not \( A \times B \times C\).

**Details and assumptions**

The letters represent digits. Any of them can be any of the digits.
