@Sanjay: suppose Max_INT range is 300 now suppose
end=300 and start =2 now using (start+end)/2 i.e *302*/2 but 302 goes out of range for and interger type as assumed... but if we use start + (end-start)/2 THEN 2 + (300-2)/2 , i.e 2+ *298*/2 here 298 < 300 hence it within int_Max range which was assumed 300..
