What is sequence in an algorithm?
Sequence is a control structure where the computer executes the instructions in the order they are written. Each instruction cannot be executed until the previous instruction is completed.
Example: This pseudocode algorithm uses the sequential instructions INPUT and OUTPUT and will simply execute the instructions in sequence, starting at the top . . .
