The general format to shift the bit is as follows: variable << or >> number of places to shift; For example, if a=10. a>>2; //shifts two bits. a>>4; //shifts 4 bits. Java provides the following types of shift operators: Signed Right Shift Operator or Bitwise Right Shift Operator. WebTime complexity of all bitwise operations is O(1). Infact these are faster than the arithmatic operations, this is the reason why experienced competitive coders use the shift operators instead of * or /.
