Or
Problem
Problem Statement:
how many distinct numbers can be generated by doing bitwise OR of one or more integers between A and B (inclusive)?
Input Format:
input contains two integers A and B
Output Format:
Print the number of possible Integer that can be genrated .
Constraints :
- 1≤A≤B<260
- A and B are integers.
Time Limit: 2
Memory Limit: 256
Source Limit:
Explanation
In this case, A=7 and B=9. There are four integers that can be generated doing the bitwise OR of a non-empty subset of {7, 8, 9}: 7, 8, 9 and 15
