Shifting would be - adding one element at the end and moving the start pointer by one. This would work in O (1). Using BitArray might be a good idea if you have a series of bit operations and not only this one shift. – George Mamaladze Dec 9, 2011 at 19:42
WebMay 5, 2009 · Second type cast is technically redundant. You could shorten it up by writing (long)left << 32 (uint)right. this shifts the first int left by 32 bits (the length of an int), then ors in the second int, so you end up with the two ints concatentated together in a long. Be careful with the sign bit. WebJun 16, 2009 · The problem is that, in the first function, bits[0] returns the least significant bit, but the second function is returning the most significant bit.

When both bits are 1 then the result bit is 1 if not 0. Bitwise OR ( ): Each bit from the first operand is associated with that of its second operand.
