Lexicographically preceding permutation, C/C++ Programming

Assignment Help:
Given an integer n and a permutation of numbers 1, 2 ... , n-1, n write a program to print the permutation that lexicographically precedes the given input permutation. If the given permutation is the lexicographically least permutation, then print the input permutation itself.

Input Format:
First line is the value of integer n: 1 <= n <= 1,000,000
Second line is a space separated list of integers 1 2 ... n permuted in some random order

Output Format: Output a single line containing a space separated list of integers which is the lexicographically preceding permutation of the input permutation.
