Write a function ReverseDigit that takes an integer as a pa$-$ rameter and returns the number with its digits reversed. Note that your output should exclude leading zeros in the reversed number $($see the $2$nd and the $4$th examples below$)$ and keep the sign of the number intact, i$.$e$.$ positive $($and negative$)$ numbers remain positive $($and negative, respectively$).$ Call the function from the main function to test it$.$Sample input and corresponding output:Enter an integer: $609$The number with the digits reversed is: $906$Enter an integer: $5600$The number with the digits reversed is: $65$Enter an integer: $-1029$The number with the digits reversed is: $-9201$ Write a function ReverseDigit that takes an integer as a parameter and returns the number with its digits reversed.
