WebThere are two unconditional jumps in 8051 − LJMP (long jump) − LJMP is 3-byte instruction in which the first byte represents opcode, and the second and third bytes represent the 16-bit address of the target location. The 2-byte target address is to allow a jump to any memory location from 0000 to FFFFH. Web30 May 2009 · The main idea of the below solution is – Loop while n is not 0 and in loop unset one of the set bits and invert parity. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. Algorithm: getParity (n) 1. Initialize parity = 0 2. Loop while n != 0 a. Invert parity parity = !parity b.
