Conclusion
Logical instructions typically work on a bit by bit basis, although some processors use the entire contents of the operands as whole flags (zero or not zero input, zero or negative one output). Typical logical operations include logical negation or logical complement (NOT), logical and (AND), logical inclusive or (OR), and logical exclusive or (XOR). Logical tests are a comparison of a value to a bit string (or operand treated as a bit string) of all zeros. Some processors have an instruction that sets or clears a bit or byte in registers or memory based on the processor condition codes.
Therefore, developing 3 algorithms which were described in this work, was very interesting. Moreover, it is possible to see how they work on the examples.
Flowcharts show how is algorithms works. A Flow Chart is a diagrammatic representation that illustrates the sequence of operations to be performed to gain the solution of a problem.
