Returns the bit value at offset in the string value stored at key.

When offset is beyond the string length, the string is assumed to be a contiguous space with 0 bits. When key does not exist it is assumed to be an empty string, so offset is always out of range and the value is also assumed to be a contiguous space with 0 bits.

Return

Integer reply: the bit value stored at offset.
