"content":"<p>You are given a string <code>s</code> of <strong>even length</strong> consisting of digits from <code>0</code> to <code>9</code>, and two integers <code>a</code> and <code>b</code>.</p>\n\n<p>You can apply either of the following two operations any number of times and in any order on <code>s</code>:</p>\n\n<ul>\n\t<li>Add <code>a</code> to all odd indices of <code>s</code> <strong>(0-indexed)</strong>. Digits post <code>9</code> are cycled back to <code>0</code>. For example, if <code>s = "3456"</code> and <code>a = 5</code>, <code>s</code> becomes <code>"3951"</code>.</li>\n\t<li>Rotate <code>s</code> to the right by <code>b</code> positions.
