Example

The example below showcases the use of the .push_front() method:

#include <iostream>
#include <deque>

int main() {
  // Create a deque of integers
  std::deque<int> numbers;

  // Use .push_front() to add elements to the beginning of the deque
  numbers.push_front(30);
  numbers.push_front(20);
  numbers.push_front(10);

  // Display the elements of the deque
  std::cout << "Deque contents: ";
  for (int num : numbers) {
    std::cout << num << " ";
  }
  std::cout << std::endl;

  return 0;
}
