Solution

To reverse the first half and second half of the array, we can follow these steps:

  1. Read the size of the array (N) from the input.
  2. Read the array elements from the input and store them in an array.
  3. Calculate the midpoint of the array by dividing the size (N) by 2.
  4. Iterate from index 0 to the midpoint - 1 and swap each element with its corresponding element from the second half of the array.
  5. Print the reversed array.

Here is the code in C to implement the above steps:

#include <stdio.h>

int main() {
    int N;
    scanf("%d", &N);

    int arr[N];
    for (int i = 0; i < N; i++) {
        scanf("%d", &arr[i]);
    }

    int midpoint = N / 2;
    for (int i = 0; i < midpoint; i++) {
        int temp = arr[i];
        arr[i] = arr[N - i - 1];
        arr[N - i - 1] = temp;
    }

    for (int i = 0; i < N; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}

This code reads the size of the array, reads the array elements, reverses the first half and second half of the array, and then prints the reversed array.

Write a program that takes an array of integers as input and prints all its subarrays, ensuring that they are sorted based on the forward direction and the count of elements.Constraints:The length of the array is at least 1 and at most 100.Each element of the array is an integer between -1000 and 1000.Input:The input consists of two lines. The first line contains an integer, n, which is the length of the array. The second line contains n space-separated integers, representing the elements of the array.Output:The program should print all the subarrays of the given array in increasing order, one subarray per line.
