If 'P' stands for '$÷$ ', 'Q' stands for '$\times$ ', 'R' stands for '$+$ ' and 'S' stands for '$-$ ', what will come in place of the question mark (?) in the following equation?
$$174\text{ P }2\text{ S }45\text{ R }(16\text{ P }4)\text{ Q }5\text{ S }26=\text{?}$$

Given the code representation for mathematical operations:
* $\text{P}\to ÷$
* $\text{Q}\to \times$
* $\text{R}\to +$
* $\text{S}\to -$

Substituting these operators into the given expression:

$$174÷2-45+(16÷4)\times 5-26$$

Now, solve using the BODMAS rule:

1. Bracket (Parentheses):

$$16÷4=4$$

The expression becomes:

$$174÷2-45+4\times 5-26$$

2. Division:

$$174÷2=87$$

The expression becomes:

$$87-45+4\times 5-26$$

3. Multiplication:

$$4\times 5=20$$

The expression becomes:

$$87-45+20-26$$

4. Addition & Subtraction:

$$87-45=42$$

$$42+20=62$$

$$62-26=36$$

Hence, the value in place of (?) is 36.
