Solution
Here is a Python solution for the problem:
def second_largest_digit(n):
# Convert the number to a list of its digits
digits = [int(d) for d in str(n)]
# If there is only one unique digit, return -1
if len(set(digits)) < 2:
return -1
# Otherwise, return the second largest digit
else:
return sorted(list(set(digits)))[-2]
# Test the function with the provided examples
print(second_largest_digit(9765)) # Output: 7
print(second_largest_digit(11)) # Output: -1
print(second_largest_digit(99856)) # Output: 8
print(second_largest_digit(555)) # Output: -1
This program works by first converting the input number to a list of its digits. It then checks if there is more than one unique digit. If there is only one unique digit, it returns -1. Otherwise, it sorts the list of unique digits and returns the second largest one.

Single File Programming QuestionProblem StatementSathish wants to create a program to check whether its digits are in descending order. The program should output "Yes" if the digits are in descending order and "No" otherwise. He wants to get an integer input that has unique digits in it and determine whether the number meets this condition. Write a program to assist Sathish in completing this task using the goto statement.For example, In the number 4321, all the digits are in descending order.Input format :The input consists of an integer N, that represents the number to be checked.Output format :If the digits of N are in descending order, the output prints "Yes".Else, the output prints "No".Refer to the sample output for formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:1 ≤ N < 105Sample test cases :Input 1 :2589Output 1 :NoInput 2 :4321Output 2 :YesInput 3 :93578Output 3 :No
