You are given a string <code>s</code> consisting of digits.

Return <code>true</code> if the absolute difference between every pair of adjacent digits is at most 2, otherwise return <code>false</code>.

The absolute difference between <code>a</code> and <code>b</code> is defined as <code>abs(a - b)</code>.

&nbsp;
Example 1:

<div class="example-block">
Input: s = &quot;132&quot;

Output: true

Explanation:

<ul>
	<li>The absolute difference between digits at <code>s[0]</code> and <code>s[1]</code> is <code>abs(1 - 3) = 2</code>.</li>
	<li>The absolute difference between digits at <code>s[1]</code> and <code>s[2]</code> is <code>abs(3 - 2) = 1</code>.</li>
	<li>Since both differences are at most 2, the answer is true.</li>
</ul>
</div>

Example 2:

<div class="example-block">
Input: s = &quot;129&quot;

Output: false

Explanation:

<ul>
	<li>The absolute difference between digits at <code>s[0]</code> and <code>s[1]</code> is <code>abs(1 - 2) = 1</code>.</li>
	<li>The absolute difference between digits at <code>s[1]</code> and <code>s[2]</code> is <code>abs(2 - 9) = 7</code>, which is greater than 2.</li>
	<li>Therefore, the answer is false.</li>
</ul>
</div>

&nbsp;
Constraints:

<ul>
	<li><code>2 &lt;= s.length &lt;= 100</code></li>
	<li><code>s</code> consists only of digits.</li>
</ul>

You are given a string s consisting of digits.

Return true if the absolute difference between every pair of adjacent digits is at most 2, otherwise return false.

The absolute difference between a and b is defined as abs(a - b).

 

Example 1:

Input: s = "132"

Output: true

Explanation:

 * The absolute difference between digits at s[0] and s[1] is abs(1 - 3) = 2.
 * The absolute difference between digits at s[1] and s[2] is abs(3 - 2) = 1.
 * Since both differences are at most 2, the answer is true.

Example 2:

Input: s = "129"

Output: false

Explanation:

 * The absolute difference between digits at s[0] and s[1] is abs(1 - 2) = 1.
 * The absolute difference between digits at s[1] and s[2] is abs(2 - 9) = 7, which is greater than 2.
 * Therefore, the answer is false.

 

Constraints:

 * 2 <= s.length <= 100
 * s consists only of digits.
