Final Answer:
Using a stack to reverse the order of elements is a common and effective technique in programming, as demonstrated in all three scenarios.
Step-by-step explanation:
1. Reverse Integer Values:
def reverse_integers(nums):
stack = []
for num in nums:
stack.append(num)
reversed_nums = []
while stack:
reversed_nums.append(stack.pop())
return reversed_nums
# Example usage
numbers = [1, 2, 3, 4, 5]
reversed_numbers = reverse_integers(numbers)
print(f"Reversed integers: {reversed_numbers}")
2. Reverse String:
#include <stack>
std::string reverse_string(const std::string& text) {
std::stack<char> stack;
for (char c : text) {
stack.push(c);
}
std::string reversed_text;
while (!stack.empty()) {
reversed_text += stack.top();
stack.pop();
}
return reversed_text;
}
// Example usage
std::string str = "ABCDEFGHIJ";
std::string reversed_str = reverse_string(str);
std::cout << "Reversed string: " << reversed_str << std::endl;
3. Reverse C-string Array:
C++
#include <stack>
template <typename T>
void reverse_c_strings(T* c_strings, int size) {
std::stack<T*> stack;
for (int i = 0; i < size; ++i) {
stack.push(&c_strings[i]);
}
for (int i = 0; i < size; ++i) {
c_strings[i] = stack.top();
stack.pop();
}
}
// Example usage
char* friend_names[] = {"Jonathan", "Josie", "Joseph", "Jocelyn"};
int num_friends = sizeof(friend_names) / sizeof(friend_names[0]);
reverse_c_strings(friend_names, num_friends);
for (int i = 0; i < num_friends; ++i) {
std::cout << friend_names[i] << " ";
}
std::cout << std::endl;
These examples demonstrate how to use a stack to efficiently reverse integer values, strings, and C-strings in different programming languages. You can adapt these examples to your specific needs and programming language.
