Print numbers with digits 0 and 1 only such that their sum is N

Given a number N, the task is to find the required numbers consist of only 0 and 1 digit whose sum is equal to N.

Example:

Input: 9 
Output: 1 1 1 1 1 1 1 1 1 
Only numbers smaller than or equal to 9 with 
digits 0 and 1 only are 0 and 1 itself.
So to get 9, we have to add 1 - 9 times.

Input: 31
Output: 11 10 10

Approach:

Initialize product p to 1 and m to zero.
Create the vector that stores the resultant integer counts of 0s and 1s.
Loop for N and check if N is multiple of 10 if yes get the decimal and update p by multiplying 10 and store this value in a vector and decrease N by m do this for each decimal and print the total size of vector.
Finally traverse the vector and print the elements.

Below is the implementation of the above approach.

C++

// C++ implementation of the above approach
#include <bits/stdc++.h>
using namespace std;
 
// Function to count the numbers
int findNumbers(int N)
{
    // Initialize vector array that store
    // result.
    vector<int> v;
 
    // Get the each decimal and find its
    // count store in vector.
    while (N) {
 
        int n = N, m = 0, p = 1;
        while (n) {
 
            // find decimal
            if (n % 10)
              m += p;
 
            n /= 10;
            p *= 10;
        }
 
        v.push_back(m);
 
        // Decrement N by m for each decimal
        N -= m;
    }
 
    // Loop for each element of vector
    // And print its content.
    for (int i = 0; i < v.size(); i++)
        cout << " " << v[i];
 
    return 0;
