If $\text{FEMALE}$ is coded as $654135$, then $\text{LEAF}$ will be coded as _______.

Let's correspond each letter of the word $\text{FEMALE}$ to its assigned digits from the given code:
$$\text{F}\to 6$$

$$\text{E}\to 5$$

$$\text{M}\to 4$$

$$\text{A}\to 1$$

$$\text{L}\to 3$$

$$\text{E}\to 5$$

Using these direct letter-to-digit values, we find the code for $\text{LEAF}$:

$$\text{L}\to 3$$

$$\text{E}\to 5$$

$$\text{A}\to 1$$

$$\text{F}\to 6$$

Thus, $\text{LEAF}$ is coded as $3516$.
