Problem
An array is a series of elements of the same type placed in
contiguous memory locations that can be individually referenced by
adding an index to a unique identifier.
Declaration:
int arr[10]; //Declares an array named arr of size 10, i.e; you can store 10 integers.
Accessing elements of an array:
Indexing in arrays starts from 0.So the first element is stored at arr[0],the second element at arr[1]...arr[9]
You'll be given an array of N integers and you have to print the integers in the reverse order.
Input Format
The first line of the input contains N,where N is the number of integers.The next line contains N integers separated by a space.
Constraints
- 1<= N <= 1000
- 1<= Ai <= 10000 where Ai is the ith integer in the array.
Output Format
Print the N integers of the array in the reverse order in a single line separated by a space.
Sample Input
4 1 4 3 2
Sample Output
2 3 4 1
Solution :-
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | #include <cmath> #include <cstdio> #include <vector> #include <iostream> #include <algorithm> #define MAX 10000 using namespace std; int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */ int a[MAX], N,i; cin>>N; for(i=1;i<=N;i++) { cin>>a[i]; } for(i=0;i<N;i++) { cout<<a[N-i]<<" "; } return 0; } |

Hey, I am Parthe Omkar
How does this solution even work!?
First basic of array is array index starts from 0 not from 1 in first for loop i = 1.
codeworld19 who provided this solution lacks even basic understanding of array.
bro, I just wanted to ask same question : /
