Hexadecimal number bit manipulation practice

June 26, 2016

Need to work on problem solving, AorB, how to design a few simple APIs first?

Write a few function to check bit by bit from right to left, or left to right.

A|B = C, to make A as small as possible, with maximum number of bits to update.

For example,
11001000     A
00000000     B
______________
11001000     C

If there are 2 more bits allowed to be update, then to make A smallest as possible, update A's leftmost bit to 0, and update C's leftmost bit to 1.

01001000   A'
10000000   B'
___________
11001000   C
