按照 C# 中第一列的排序算法对第二列的二维数组进行排序

Question

I have a [2,5000] array of strings that I want to sort just based on the first row, but I want second row to follow that sorting algorithm.

Can I get a lead idea on how I should be approaching this situation?

Edit: My array looks like

{15, 13, 16, 19, 25, 29, 11} {wed 12, thu 13, fri 14, sat 15, sun 16, mon 17}

and I want it as

{29, 25, 19, 16, 15, 13, 11} {sun 16, sat 15, fri 14, wed 12, thu 13, mon 17}

Answer 1

Don't create a two dimensional array; create a single dimensional array of some class that has two properties, and then sort that based on a custom comparer that only compares one of the values.

Answer 2

I suppose this is an assignment. You need to code a sorting algorithm (there are many, including some very simple ones ), and while sorting the first row, perform all the swaps on both the first and second row.

ie a sorting algorithm might look like

void Sort(string[] array) {
    // some logic to loop over the array, determine which elements to swap
        swap(array[x], array[y]);
}

basically you want to code something like

void Sort(string[] firstRow, string[] secondRow) {
    // some logic to loop over firstRow, determine which elements to swap
        swap(firstRow[x], firstRow[y]);
        swap(secondRow[x], secondRow[y]);
}
