<div>In the image above vertex <span class="ltx_Math" contenteditable="false" data-equation="1,2">\(1,2\)</span> and <span class="ltx_Math" contenteditable="false" data-equation="3">\(3\)</span> are kings because they can each get to every other vertex in at most <span class="ltx_Math" contenteditable="false" data-equation="2">\(2\)</span> steps. Lets take a look at vertex <span class="ltx_Math" contenteditable="false" data-equation="1">\(1\)</span>, <span class="ltx_Math" contenteditable="false" data-equation="1\rightarrow3">\(1\rightarrow3\)</span>, <span class="ltx_Math" contenteditable="false" data-equation="1\rightarrow3\rightarrow2">\(1\rightarrow3\rightarrow2\)</span>, and <span class="ltx_Math" contenteditable="false" data-equation="1\rightarrow3\rightarrow4">\(1\rightarrow3\rightarrow4\)</span>. The reason why vertex <span class="ltx_Math" contenteditable="false" data-equation="4">\(4\)</span> is not a king is because it would take more than <span class="ltx_Math" contenteditable="false" data-equation="2">\(2\)</span> steps to reach vertex <span class="ltx_Math" contenteditable="false" data-equation="2">\(2\)</span>.<br></div>
