Using the concept of a string stack, you can represent a circuit as a series of digits that are compared in a specific way. These comparisons are based on the use of the order operator (==), which means that the operands are compared in the same order as their strings, without converting them into numbers. This is the same concept used in the bitwise AND operation, as well as the left and right shift operations. The same rules apply, but the order operators can be used on numbers, strings, or both, depending on the type of operand.
A bitwise right shift operation, __shr, is similar to the left shift operation, __shl, and is used to represent a circuit in which the same current flows both from the collector and the emitter. Similarly, a bitwise left shift operation, __shr, can be used to represent a circuit in which the output of a PNP transistor is almost identical to the input of a similar transistor. In this case, the voltage on the upper emitter resistor reproduces the logic level on the bottom of the circuit. The same logic is represented by the daisy chain, which continues up the stack of batteries.
Similarly, a boolean value, or true and false, can be represented by the if-else statement, which compares two conditions. This is the same method as the equality (==) comparison, except that it compares the types and values of the operands instead of just their strings.
