title: How to represent the max power possible
body: <p>Kind of a math question, but very programming related. Doing some Big-O problems and I have an algorithm where a for loop will run n times, where k = input size, n = max power of 4 where <code>(k)/(4^n) &gt;= 1</code>. How can I represent <strong><em>max power of 4</em></strong> where <code>(k)/(4^n) &gt;= 1</code> in one mathematic statement?</p>
