Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n)
{
    // Write your pointer-based logic here
    int *pEnd = mem + n - 1;
    int temp = *mem;
    ++mem;
    int indx =0; 

    while (mem <= pEnd)

            ++mem;
            ++indx; 
        }
        else if (temp < *mem)
        {
            int check = *mem - temp;
            if (check == 1)
            {
                while (check)
                {

                    // k++;

                    if (check == 1)

int main()

    int n, arr[100];
    scanf("%d", &n);

    for (int i = 0; i < n; i++)

    }

    int res = find_pattern(arr, n);
