This machine runs for 9 seconds and 49 milliseconds.Note: There is no bit type of programming language to implement bit manipulationTake the int type under 32-bit operating system as an example. If you need to apply n bits, you need to have a[n/32+1] int type to allow the next n bit (of course, some bits in the last int are wasted)When the position I is 1, you can use the following actions:The first bit must be in the number of int array A (I/32), the offset is (i%32), the I position is
