My code

#include <iostream>
using namespace std;

void printWavePattern(int N) {
    int width = N * 4 - 1; // Total width of the pattern

    for (int i = 0; i < N; i++) {  
        for (int j = 0; j < width; j++) {  
            if ((i == 0 || i == N-1) && (j % 4 == 0 || j % 4 == 1)) // First & Last row pattern
                cout << "*";
            else if (i == 1 && j % 4 == 2) // Middle row pattern (diagonal)
                cout << "*";
            else
                cout << " ";
