Multi-Language (Coding): Frequency of Integer in Array Test

The question presents a problem where we are given an integer N and an array of integers arr, and we are tasked with finding the total number of occurrences of N in arr. The function count_occurrences should take in two arguments - an integer N and an array of integers arr - and return an integer that represents the total number of occurrences of N in arr. If N is not present in arr, the function should return 0.

To solve this problem, we can use a simple approach where we iterate through the array and check each element to see if it matches N. If it does, we can increment a counter variable. After iterating through the entire array, we can return the counter variable that represents the total number of occurrences of N in arr.

Here's an algorithm that summarizes the steps:

Initialize a counter variable to 0. Iterate through each element in the array arr. Check if the current element is equal to N. If it is, increment the counter variable by 1. After iterating through the entire array, return the counter variable. If N is not present in arr, return 0.
