Fix a typo in "Combination Sum"

Runzhen Wang · Runzhen Wang · commit cc34095bc0b8 · 2014-10-27T22:22:44.000-07:00
On the problem's website : https://oj.leetcode.com/problems/combination-sum/ the description of the problem had changed. As the Note says, elements are in non-descending order, the greater-than sign may lead to misunderstanding, and Leetcode had changed it to less-and-equal-than sign. so I updated the content in the source file.

 \item All numbers (including target) will be positive integers.
-\item Elements in a combination ($a_1, a_2, ..., a_k$) must be in non-descending order. (ie, $a_1 > a_2 > ... > a_k$).
+\item Elements in a combination ($a_1, a_2, ..., a_k$) must be in non-descending order. (ie, $a_1 \leq a_2 \leq ... \leq a_k$).
 \item The solution set must not contain duplicate combinations.
