Given an integer n. No-Zero integer is a positive integer which doesn't contain any 0 in its decimal representation. Return a list of two integers [A, B] where: A and B are No-Zero integers. A + B = n It's guarateed that there is at least one
You are given an array nums of non-negative integers. nums is considered special if there exists a number x such that there are exactly x numbers in nums that are greater than or equal to x. Notice that x does not have to be an element in n

思路 题目要求： \[na+b-c=m \]我们可以转换为 \[na-m=c-b \]然后\(c-b\)是固定不变的，我们去枚举a，在枚举的a的时候我们发现要使等式尽可能的成立只有让\(na-m\)的差值绝对值越小越好，然后我们会发现\(na\)在\(m\)的左右两侧时，差值绝对值最小。 比如说 \[2*a……m……3*a \]我们让m将
