Task 4.1. Assign each letter a digit $1,2,3,4,5$ so that all inequalities are satisfied.

$$
3>\mathrm{A}>\mathrm{M}<\mathrm{E}<\mathrm{H}<\mathrm{A}
$$

Different letters must correspond to different digits. Write the number ZAMENA as your answer.
Answer: 541234.

Solution. From the condition, it follows that $\mathrm{M}<\mathrm{E}<\mathrm{H}<\mathrm{A}<3$. The numbers from 1 to 5 are uniquely ordered, so $\mathrm{M}=1, \mathrm{E}=2, \mathrm{H}=3, \mathrm{~A}=4,3=5$. Then ZAMENA $=541234$.
