868 - Binary Gap.
Easy
Given a positive integer
n
, find and return the longest distance between any two adjacent1
's in the binary representation ofn
. If there are no two adjacent1
's, return0
.Two
1
's are adjacent if there are only0
's separating them (possibly no0
's). The distance between two1
's is the absolute difference between their bit positions. For example, the two1
's in"1001"
have a distance of 3.Example 1:
Input: n = 22
Output: 2
Explanation: 22 in binary is "10110".
The first adjacent pair of 1's is "10110" with a distance of 2.
The second adjacent pair of 1's is "10110" with a distance of 1.
The answer is the largest of these two distances, which is 2.
Note that "10110" is not a valid pair since there is a 1 separating the two 1's underlined.
Example 2:
Input: n = 8
Output: 0
Explanation: 8 in binary is "1000". There are not any adjacent pairs of 1's in the binary representation of 8, so we return 0.
Example 3:
Input: n = 5
Output: 2
Explanation: 5 in binary is "101".
Constraints:
<code>1 <= n <= 10<sup>9</sup></code>
