What Is The Approach Implemented In The Following Codep Pre #1170

 #include<iostream> using namespace std; void printArray(int p[], int n) { for (int i = 0; i <= n-1; i++) cout << p[i] << " "; cout << endl; } void func1(int n) { int p[n]; int k = 0; p[k] = n; while (true) { printArray(p, k+1); int rem_val = 0; while (k >= 0 && p[k] == 1) { rem_val += p[k]; k--; } if (k < 0) return; p[k]--; rem_val++; while (rem_val > p[k]) { p[k+1] = p[k]; rem_val = rem_val - p[k]; k++; } p[k+1] = rem_val; k++; } }  int main() { int n; cin>>n; func1(n); return 0; }
