A palindromic number is a number that remains the same when its
digits are reversed. For examples, 1, 11, 99, 121 are palindromic.
Write a program that takes one array of 10 positive integers as
input and output all the palindromic numbers in this array. We
assume that each input number is valid, i.e., a positive
integer.
Hint: You can consider the following steps to check whether a
number (e.g., 121) is palindromic • Store this number to one
variable,...

In a three-digit lottery, each of the three digits is supposed
to have the same probability of occurrence (counting initial blanks
as zeros, e.g., 32 is treated as 032). The table shows the
frequency of occurrence of each digit for 90 consecutive daily
three-digit drawings.
