Question 1110669
.
Had this problem be formulated CORRECTLY, it would say if repetition is allowed or not.


<pre>
    English alphabet has 26 letters (we consider only capitals).


    So, if repetition  <U>IS ALLOWED</U>,  we have {{{26^3}}}  four-letter  strings starting with L.


    If, on contrary, repetition  <U>IS NOT ALLOWED</U>, we have 25*24*23 four-letter strings starting with L.
