For correctness, not inherently flawed, but one showstopper bug.You're checking the bit at bitindex with num1 & position, but instead of exchanging those bits you use num1 << bitindex instead of 1 << bitindex.. The very first step of this, with bitindex = 0, will zero both numbers if one is … In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are presented as two-operand instructions where the result replaces one of the input operands. small flower buttercup
