Function numberTrianglePattern – CTS PATTERN

You are required to complete the given code by implementing the logic for the function. You can click on Run anytime to check the compilation/execution status of the program. You can use printf to debug your code. The submitted code should be logically/syntactically correct and pass all test cases. Do not write the main() function as it is not required. 

Code Approach: For this question, you will need to implement the logic for the program.

The function numberTrianglePattern(int N) accepts an integer N as the input. The function is supposed to print the pattern as shown in the Example Input/Output Sections.

Your task is to fill in the missing lines of code so that the program passes all test cases.

Example Input/Output 1:
Input:
4

Output:
      1 
    2 3 2 
  3 4 5 4 3 
4 5 6 7 6 5 4 

Example Input/Output 2:
Input:
5

Output:
        1 
      2 3 2 
    3 4 5 4 3 
  4 5 6 7 6 5 4 
5 6 7 8 9 8 7 6 5

void numberTrianglePattern(int N)
{
  int dup;
  for(int i=1;i<=N;i++)
  {
    dup=i;
    for(int j=1;j<=i;j++)
    {
      printf("%d ",dup);
      dup+=1;
    }
    dup-=2;
    for(int j=dup;j>=i;j--)
    {
      printf("%d ",j);
    }
    printf("n");
  }
