<p>Given a collection of candidate numbers (<code>candidates</code>) and a target number (<code>target</code>), find all unique combinations in <code>candidates</code> where the candidate numbers sums to <code>target</code>.</p>
<p>Each number in <code>candidates</code> may only be used <strong>once</strong> in the combination.</p>
<p><strong>Note:</strong></p>
<ul>
<li>All numbers (including <code>target</code>) will be positive integers.</li>
<li>The solution set must not contain duplicate combinations.</li>
</ul>
<p><strong>Example 1:</strong></p>
<pre>
<strong>Input:</strong> candidates = <code>[10,1,2,7,6,1,5]</code>, target = <code>8</code>,
<strong>A solution set is:</strong>
[
[1, 7],
[1, 2, 5],
[2, 6],
[1, 1, 6]
