An array is a type of data structure that stores elements of the same type in a contiguous block of memory. In an array, , of size , each memory location has some unique index, (where ), that can be referenced as (you may also see it written as ).
Given an array, , of integers, print each element in reverse order as a single line of space-separated integers.
Note: If you've already solved our C++ domain's Arrays Introduction challenge, you may want to skip this.
Input Format
The first line contains an integer, (the number of integers in ).
The second line contains space-separated integers describing .
The second line contains space-separated integers describing .
Output Format
Print all integers in in reverse order as a single line of space-separated integers.
Sample Input
4
1 4 3 2
Sample Output
2 3 4 1
Solution: #include <math.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <assert.h> #include <limits.h> #include <stdbool.h> int main(){ int n; scanf("%d",&n); int *arr = malloc(sizeof(int) * n); for(int arr_i = 0; arr_i < n; arr_i++){ scanf("%d",&arr[arr_i]); } for (int arr_i = n - 1; arr_i >= 0; arr_i--) { printf("%d ", arr[arr_i]); } return 0; }
