# Program to print N minimum elements from list of integers

Given a list of integers, the task is to generate another list with N minimum elements.

Examples:

```Input: {23, 1, 6, 2, 90}
Output: {1, 2}

Input: {34, 21, 56, 42, 89, 90, -1}
Output: {-1, 21}
```

Approach: The idea is to use the concept used in Find the smallest and second smallest elements in an array.

• First, find the smallest number in the given list.
• Then add that current minimum element to another list that will contain the N minimum elements.
• Remove the current minimum element from the given list.
• Continue with the same process until the N minimum elements are found.

Below is the implementation of the above approach:

## C++

 `// C++ program to find N  ` `// minimum elements ` `#include ` `using` `namespace` `std; ` ` `  `void` `Nminelements(vector<``int``>list1, ``int` `N) ` `{ ` `    ``vector<``int``> final_list; ` `    ``int` `n = list1.size(); ` `    ``for` `(``int` `i = 0; i < N; i++)  ` `    ``{ ` `        ``int` `min1 = 9999999; ` `        ``for` `(``int` `j = 0; j < n; j++) ` `        ``{ ` `            ``if` `(list1[j] < min1) ` `                ``min1 = list1[j]; ` `        ``} ` `         `  `        ``// remove minimum element  ` `        ``// from list so that it do ` `        ``// not come in calculation again          ` `        ``list1.erase(``remove``(list1.begin(),  ` `                           ``list1.end(), min1),  ` `                           ``list1.end()); ` `        ``final_list.push_back(min1); ` `    ``} ` `    ``for``(``int` `i = 0; i < final_list.size(); i++) ` `    ``cout << final_list[i] << ``" "``; ` `}  ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``vector<``int``> list1 = {4, 78, 34, 10,  ` `                         ``8, 21, 11, 231}; ` `    ``int` `N = 2; ` `    ``Nminelements(list1, N); ` `} ` ` `  `// This code is contributed by Subhadeep `

## Python3

 `# Python program to find N minimum elements ` `def` `Nminelements(list1, N): ` `    ``final_list ``=``[]; ` `  `  `    ``for` `i ``in` `range``(``0``, N):     ` `        ``min1 ``=` `9999999``; ` `          `  `        ``for` `j ``in` `range``(``len``(list1)):       ` `            ``if` `list1[j]

Output:

```4 8
```
