Code:

n= int(input("enter"))
l=n*2-1
for i in range(l):
    for j in range(l):
        if(i<j):
            m=i
        else:
            m=j
        if(m<l- i):
            m=m
        else:
            m=l-i-1
        if(m<l-j):
            m=m
        else:
            m=l-j-1
        print(n-m, end=" ")
    print("")
