Each function deals with null terminated C-strings.  You can assume that any char array passed into the functions will contain valid, null-terminated data.  Your functions must have the signatures listed below.   This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2.  It should return -1 if the substring does not appear in the string. int findSubstring(char *s, char substring[])
