Problem Statement

Write a C program to count the total occurrences of a target element in a sorted array using binary search bounds.

Input Format

First line: N and Target. Second line: N sorted space-separated integers.

Output Format

Print the total occurrence count.

Constraints

1 <= N <= 1000

int main() {
    int n, target;
    if (scanf("%d %d", &n, &target) == 2) {
        int arr[n];
        for (int i = 0; i < n; i++) scanf("%d", &arr[i]);
        // Write your code here
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
