I have a C++ program where I have to rotate the array clockwise according to the given number of elements to be rotated (x). For example if the input array is
[1,2,3,4,5]given that 2 elements (denoted as x) must to rotated.
The output array should be
[3,4,5,1,2]Code:
#include <iostream>#include<algorithm>using namespace std;int main(){ int t; cin>>t; while(t--){ int n,x; cin>>n>>x; int a[n],b[x]; for(int i=0;i<n;i++){ cin>>a[i]; } copy(a,a+x,b); copy(b,b+x,a+n); n=n+x; for(int i=x;i<n;i++){ cout<<a[i]<<""; } } return 0;}What I'm doing here is that I copy the given number of elements to a new array. Later copy them back to the original array starting from 'n'. So my array will look like [1,2,3,4,5,1,2].
Later I'm printing out the array starting from the index 'x'. So that my array will look like [3,4,5,1,2].
I'm able to compile the program and I'm getting the output. But while submitting the code in a website called GeekforGeeks its complier is throwing out a Segmentation Fault (SIGSEGV).
