C++ programming

Write a function, isEverywhere(int a[], int size, int n), We'll say that a value is "everywhere" in an array if for every pair of adjacent elements in the array, at least one of the pair is the value n. Return true if the given value is everywhere in the array.

isEverywhere({1, 2, 1, 3}, 4, 1) ? true isEverywhere({1, 2, 1, 3}, 4, 2) ? false isEverywhere({1, 2, 1, 3, 4}, 5, 1) ? false

int isEverywhere (int a[ ], int size, int n) {
