Some of the problems are, as Dudeney admitted, ‘not unworthy of the attention of the advanced mathematician’.1982 The C Puzzle Book ( Alan R. Feuer) Item Preview.

Since i goes from 0 to 4, and shift goes through the sequence 1, 2, 4,8, and 16, regardless of the input. So the calculation has five fixedstages, which have been rolled up into a loop for brevity. These fivestages limit it to counting up to 32 bits (2 to the power of 5).
Ateach stage, the following is evaluated:x = (x & maski) + ((x shift) & maski);The initial input value x is the word whose bits are to be counted,and the output of each stage is fed as input to the next stage. I.e.each stage does this:x = Fi(x)Where Fi is a function of x specific to stage i. Each Fi ischaracterized by choice of mask and shift value. So the five stagesare basically:count = F4(F3(F2(F1(F0(x)))))the chained application of five functions. Based on this, you shouldbe able to draw these stages as one big flow diagram (even down to thedetail of a combinatorial circuit).Start with the abstracted version.x - F0 - F1 - F2 - F3 - F4 - countNow zoom in on the F's and draw out how they work. It isthis:F0(x) = x & mask0 + (x shift0) & mask0where mask0 is 0x55555555 and shift0 is 1.
So in other words:F0(x) = x & 0x55555555 + (x 1) & 0x55555555;At the bit level, 0x33333333 is the bit pattern 010101. Whatis going on in this expression? The left side of the + selects all ofthe even bits in the input word x. The right side, selects all of theodd bits, but shifts them one position to the right. Let's give letternames to the 32 bits, using upper case for the lower 16:let x = abcd efgh ijkl mnop ABCD EFGH IJKL MNOPWhat is x & 01? To make it clearer,let's use the underscore character to represent zero.
When we bitwise-and x with the 0x5555. Bit pattern, we get:bd fh jl np BD FH JL NPWhat about the right side?
If we shift x one bit to the right, we get:abc defg hijk lmno pABC DEFG HIJK LMNOThe P bit falls off, and a zero is shifted in. What happens when weand this with 0x5555.?ac eg ik mo AC EG IK MOAnd now these two quantities are added together, like this:bd fh jl np BD FH JL NP+ ac eg ik mo AC EG IK MONote how there are zeros in every other column. These zeros mean thatthere is no carry in the addition. For instance if adding P and O inthe least significant bit column produces a carry bit, that carry bitwill add to the two zeros in the second column. There will be nofurther carry into the third column. Download spyhunter 4 full patch. So essentially, this addition isreally 16 independent additions withiin the 32 bit word, namelyb d f+ a + c +e.
And so onDo you see what is going on? The bits are being added togetherpairwise to produce 16 partial results of two bits each:bits 30 and 31: (a + b)bits 28 and 29: (c + d)bits 26 and 27: (e + f)and so on.In the next stage, the same pattern is repeated, but it's widened to atwo bit addition producing a four bit result. The masking pattern is0x3333 which is 11, and the shift is two. It pairs the twobit groups together and adds them.bits 28-31: ((a + b) + (c + d))bits 24-27: ((e + f) + (g + h))Ultimately, this process will yield the sum:a + b + c + d + e +. + p + A + B +. + PAnd this sum is, of course, the number of bits in the original word,since each letter represents a bit, 0 or 1. The algorithm exploits theability of the machine to manipulate word quantities in order topartially parallelize this addition.That's approximately how you understand something.
The level of detailyou have to go in drawing it out depends on your experience and mentalpower. Someone very intelligent or experienced or both will recognizethe pattern instantly and just see what is going on without having towrite out the process.
