Task: Rotate an array of size N by d elements, where d <= N. Example: Input: 1 5 1 2 3 4 5 Output: 3 4 5 1 2 Here is the Code: Program in C++: #include<iostream> using namespace std; int main() { int t; cin>>t; while(t--) { int n; cin>>n; int a[n]; for(int i=0;i<n;i++) { cin>>a[i]; } int d; cin>>d; // code logic for(int i=0;i<d;i++) { int j=0,temp=a[0]; while(j<n-1) { a[j]=a[j+1]; j++; } a[j]=temp; } for(int i=0;i<n;i++) { cout<<a[i]<<" "; } cout<<endl; } return 0; } Here is the Video:
