Problem Statement

Write a C++ program simulating an ATM cash withdrawal machine with currency denomination counts.

Input Format

An integer amount representing the total cash requested.

Output Format

Print the number of 100, 50, and 10 notes required.

Constraints

0 <= Amount <= 100000

100s: 4
50s: 1
10s: 3

Explanation

Uses greedy division to determine standard currency breakdown.

Starter Code

#include <iostream>

int main() {
    int amount;
    if (std::cin >> amount) {
        // Write your ATM denomination logic here
    }
    return 0;
}

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

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
