【问题描述】：

I have 3 arrays. Lets say the first array has 3 elements, second array has 2 elements, and third array has 5 elements. When I concatenate them the array[3] will go to first element of the second array, array[6] will go to the second element of third array, because I first concatenate the first array with the second. If I concatenate the first array with the third, then concatenate the second array, array[3] will point to the first element of the third array.
