Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>


int find_pattern(int *mem, int n) {
int *p1=mem;
int *p2=mem+1;
int *p3=mem+2;
for(int i=0; i<n;i++){
if((*p1 + 1==*p2)&&(*p2 + 1==*p3)){
    return i;
   }
p1++;
p2++;
p3++;
}
return -1;
}


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


    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }


    int res = find_pattern(arr, n);
    printf("%d", res);


    return 0;
}
