//You are given an array of strings (one line, space-delimited). Sort the array using the Bubble sort or Insertion sort algorithms. //Instead of comparing if one string is smaller than the other (which you can’t do), you can use the string.CompareTo(str) method. Once //the array is sorted, print it on the console, separating the elements by spaces.
