Program sorttest4 generates an array of randomized mixed-case strings. You will note that, by default, all uppercase characters sort before the lowercase characters due to their underlying ASCII codes. For this assignment, modify program sorttest4 such that it sorts according to a case-blind comparison of only the first character of each string. In the sorted array, "car" should come before "Bus". Further, "dog" and "Duck" should be considered equal since they both with the same letter, ignoring case. You will need to modify sorttest4 (make a backup copy of the original in case you need to go back to it). Add a sort comparison function, as was done in sorttest3. Then, modify the call to the sort function (line 58) to pass your function as the third parameter
