[Jobdu] 题目1516 : 调整数组顺序使奇数位于偶数前面

 void diffOddAndEven(int a[], int n) {
     int low = , high = n - ;
     int pivot;
     while (low < high) {
         while (a[high] %  ==  && low < high)
             high--;
         while (a[low] %  ==  && low < high)
             low++;
         pivot = a[low];
         a[low] = a[high];
         a[high] = pivot;
     }
 }
