the bit to be changed and flag c is the bit value
for eg: x=fun(45,7,0)
since 45 is 0010 0101

| There is a 100-story building and you are given two eggs.
The eggs (and the building) have an interesting property
that if you throw the egg from a floor number less than X,
it will not break. And it will always brake if the floor
number is equal or greater than X. Assuming that you can
reuse the eggs which didn't broke; you got to find X in a
minimal number of throws. Give an algorithm to find X in
minimal number of throws. | | 2 |
