Dado el valor de n, es decir, el número de filas, imprima el siguiente patrón.
Ejemplos:
Input : n = 4 Output : 1 5 2 8 6 3 10 9 7 4 Input : n = 6 Output : 1 7 2 12 8 3 16 13 9 4 19 17 14 10 5 21 20 18 15 11 6
Enfoque: El enfoque es comenzar a imprimir el patrón desde el final de cada fila. Después de completar la última columna de cada fila, comience desde la penúltima columna de la segunda fila y así sucesivamente. A continuación se muestra la implementación de este enfoque:
