            "content": "<p>You are given a string <code>s</code> consisting of digits and an integer <code>k</code>.</p>\n\n<p>A <strong>round</strong> can be completed if the length of <code>s</code> is greater than <code>k</code>. In one round, do the following:</p>\n\n<ol>\n\t<li><strong>Divide</strong> <code>s</code> into <strong>consecutive groups</strong> of size <code>k</code> such that the first <code>k</code> characters are in the first group, the next <code>k</code> characters are in the second group, and so on. <strong>Note</strong> that the size of the last group can be smaller than <code>k</code>.</li>\n\t<li><strong>Replace</strong> each group of <code>s</code> with a string representing the sum of all its digits. For example, <code>&quot;346&quot;</code> is replaced with <code>&quot;13&quot;</code> because <code>3 + 4 + 6 = 13</code>.</li>\n\t<li><strong>Merge</strong> consecutive groups together to form a new string.
