Objective
Today, we’re working with binary numbers. Check out the Tutorial tab for learning materials and an instructional video!
Task
Given a base- integer, , convert it to binary (base-). Then find and print the base- integer denoting the maximum number of consecutive ‘s in ‘s binary representation. When working with different bases, it is common to show the base as a subscript.
Example
The binary representation of is . In base , there are and consecutive ones in two groups. Print the maximum, .
Input Format
A single integer, .
Constraints
