<p>The Game of Master Mind is played as follows:</p>
|
|
|
|
|
|
|
|
<p>The computer has four slots, and each slot will contain a ball that is red (R). yellow (Y). green (G) or blue (B). For example, the computer might have RGGB (Slot #1 is red, Slots #2 and #3 are green, Slot #4 is blue).</p>
|
|
|
|
|
|
|
|
<p>You, the user, are trying to guess the solution. You might, for example, guess YRGB.</p>
|
|
|
|
|
|
|
|
<p>When you guess the correct color for the correct slot, you get a "hit:' If you guess a color that exists but is in the wrong slot, you get a "pseudo-hit:' Note that a slot that is a hit can never count as a pseudo-hit.</p>
|
|
|
|
|
|
|
|
<p>For example, if the actual solution is RGBY and you guess GGRR, you have one hit and one pseudo-hit. Write a method that, given a guess and a solution, returns the number of hits and pseudo-hits.</p>
|
|
|
|
|
|
|
|
<p>Given a sequence of colors <code>solution</code>, and a <code>guess</code>, write a method that return the number of hits and pseudo-hit <code>answer</code>, where <code>answer[0]</code> is the number of hits and <code>answer[1]</code> is the number of pseudo-hit.</p>
|
|
|
|
|
|
|
|
<p><strong>Example: </strong></p>
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
<strong>Input: </strong> solution="RGBY",guess="GGRR"
|
|
|
|
<strong>Output: </strong> [1,1]
|
|
|
|
<strong>Explanation: </strong> hit once, pseudo-hit once.
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
<p><strong>Note: </strong></p>
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
<li><code>len(solution) = len(guess) = 4</code></li>
|
|
|
|
<li>There are only <code>"R"</code>,<code>"G"</code>,<code>"B"</code>,<code>"Y"</code> in <code>solution</code> and <code>guess</code>.</li>
|
|
|

</ul>
