Sir I am not able to understand what is wrong in the below code for rotate image (N X N array)

#1

//Image Rotation
//rotating the matrix clockwise by 90 degrees
//First taking the transpose of the matrix then exchanging the rows

#include
using namespace std;
int main()
{
int i,j;
int rows,column,k;
int a[100][100];

cin>>k;

for(i=0;i<k;i++)
{
    for(j=0;j<k;j++)
    {
        cin>>a[i][j];
    }
    
}


for(i=0;i<k;i++)
{
    int temp;
    temp = a[i][0];
    a[i][0] = a[i][k-1];
    a[i][k-1]=temp;
}

for(i=0;i<k;i++)
{
    for(j=0;j<k;j++)
    {
        cout<<a[j][i]<<" ";
    }
    cout<<endl;
}



return 0;

}

@harshulgarg21 According to the question, you have to rotate in anti clock wise direction. Also note that the constraints are N < 1000 and you have restricted your array to 100 x 100.
