4. Given an integer n, write a python program that finds the digit with the highest number of occurrences in n. For example, for n = 823778823478234768238 the program should return 8. def findHighestOccur(n) Test your program on the following inputs: n = 983254682376587235235 n = 767347657623764765766665 n = 923740923466234678666872628347666
