Because he cant know if particular value is in the array. For example array
is 10, 20 , 30 , 40, 50, and he must find first number greater than 34.
Anyway he can still do it using binary search. Search until either find that
value or n is 0; (n which is in binary search distance from current value,
and in beginning arraylength/2, in loop n=n/2). If the value is found just
pick next number, if not (n=0) see if current value is less or greater than
that value and than go lineary up or down depending on current value,
because you are already very close to that value.
Sorry because this doesnt belong to this newsgroup.
