Your goal is to determine the smallest difference in minutes between two of the times in the list. For example: if strArr is ["2:10pm", "1:30pm", "10:30am", "4:42pm"] then your program should return 40 because the smallest difference is between 1:30pm and 2:10pm with a difference of 40 minutes. The input array will always contain at least two elements and all of the elements will be in the correct format and unique.
