Problem: You are tasked with creating a special numbering pattern for a triangular grid of side length n.

The triangle is formed using rows such that:
- The first row has n elements.
- The second row has n - 1 elements.
- The third row has n - 2 elements.
- ...
- The last row has 1 element.

Your job is to fill this triangular grid with integers starting from 01, following a unique diagonal numbering pattern.

Numbering Rules

1. Start from the top-left element of the triangle with 01.
2. Fill the numbers diagonally downward while moving to the right.
3. Each diagonal starts from the top row and moves down toward the bottom-left of the triangle.
4. Filling must stay within the valid triangular bounds.

Hint

In each row, the difference between two consecutive entries increases by 1 with each step. The same rule applies to each column.

Input

An integer n, representing the side length of the triangle.

Output

Print n lines.
The i-th line contains n - i + 1 integers corresponding to the i-th row of the triangle.

Assumptions on Input

1 <= n <= 13

Note

- Do not print any extra messages such as:
  cout << "Enter a number"
  cout << "The computed answer is"
- Use cout only to print the computed final output.
- Do not print unnecessary spaces.
- Do not hard-code the solution.
- If any test case passes by simply printing with cout and without logic, marks will not be awarded.

Grading criterion: Overall program correctness
Rating A: "Common requirements  of a Program are correct - i.e.
 
- header (includes, using namespace, etc)
- main syntax
- variables declaration
- overall syntax"
Rating B: Problems are present in the code(eg: printing unnecessary strings, missing semicolons & braces, wrong/missing declarations, wrong header files)
Rating C: 0
Rating D: 0
Assigned grade: A
Problem: Write a C++ program to sort an array A of n numbers strictly using the given algorithm:

1. Find the minimum element in the array.
2. Swap the minimum element with the first element of the array.
3. Find the minimum element in the remaining array.
4. Swap the minimum element with the second element of the array.
5. Repeat steps 3 and 4 until the entire array is sorted.

Constraints:

* n < 25

Input Format:

* Non-negative integer n
* Array A of n elements

Output Format:

* Print the sorted array with a space between adjacent elements.

Student submission:
#include<iostream>
using namespace std;
int main()
{
	int n;
	cin>>n;
	int arr[n];
	for(int i=0;i<n;i++)
	{
		cin>>arr[i];
	}
	
	for(int k=0;k<n-1;k++)
	{	
		for(int i=k+1;i<n;i++)
		{
		
			if(arr[i]<arr[k])
			{
				int temp=arr[k];
				arr[k]=arr[i];
				arr[i]=temp;
			}	
		
		}
		
	}

	for(int i=0;i<n;i++)
	{
		cout<<arr[i]<<" ";
	}
	return 0;
