Can anybody say what's the importance of bitwise operators?

Question

and how does they help in in faster time complexity of the program?

Answer 1

Bitwise operators are important because they are the root claculation operations in computer: microprocessors are made with a lot of logical gates (transistors) giving these basics operations, which are used to build (program) more advanced functionnalities ;) This is the basis of computer logic ^^
