Keep in mind though, that [0] means the least significant bit, but we want to store them in the most significant -> least significant order, so we have to use the 7 - j instead of simply j:

Webstd::bitset:: test C++ Utilities library std::bitset Returns the value of the bit at the position pos (counting from 0). Unlike operator [], performs a bounds check and throws std::out_of_range if pos does not correspond to a valid position in the bitset. Parameters pos - position of the bit to return (counting from 0) Return valueWebC++ bitset is used as an optimization method with a fixed set of representation of the entire array or vector based bitset represented in the form of true or false and 0 and 1 which represents the unset and set state of the bitset representation within a stream.Thus, it can be concluded that bitset C++ standard library has improvised and ease the …
