Module: Sorting with comparator


Problem

3/11

Sort by last digit

Problem

You are given a sequence of integers.  Write a program that creates and sorts an array in descending order of the last digit in a number.

Input
First given number N - number of elements in sequence (1<= N <= 100). Then N numbers are written separated by a space.
 
Output
It is necessary to output an array sorted in descending order of the last digit in the number.
 
Examples
# Input Output
1 5
5 100 23 777 34 		777 5 34 23 100

time 1000 ms
memory 256 Mb

C++
Write the program below 
#include <algorithm>
#include <iostream>
#include <vector>
using namespace std;


bool cmp(int first, int second) {
    
 
}

int main() {

int N;

cin >> N;
vector<int> A (N);

    for(int i = 0; i < N; i++)
        cin>>A[i];
		        
    sort(A.begin(), A.end(), cmp );
  
    for(int i = 0;i< N; i ++)
      cout<<A[i]<<" ";

    
}
