Was asked to write a code to count the number of set bits in a 32 bit interger?
1) Lets say that I have a continuous bit pattern of 1's and there is a1 ms glitch of 0's. How do I capture the glitch and display a stationary image of it? (assuming that 1 ms is too fast for out eyes to appreciably notice the change)
