Pattern 1

---

Pattern for N = 5

 1    2   3    4   5
 11   12  13   14  15
 21   22  23   24  25
 16   17  18   19  20
 6    7    8   9   10

Input Format :

Total 'N' number of rows

Output Format :

 Pattern in 'N'number of rows

Sample Input :

4

Sample Output :

 1  2  3  4
 9 10 11 12
13 14 15 16
 5  6  7  8

Solution :

N = int(input())
a = 1
for i in range(1, N + 1):
   for j in range(a, a + N):
       print(j, end=" ")
   print()
   if i == (N + 1)//2:
      if N % 2!=0:
           a = N*(N - 2) + 1
      else:
           a = N*(N - 1) + 1
   elif (i>(N + 1)//2):
       a = a - 2*N
   else:
       a = a + 2*N

Solution :

N = int(input())
i = 1
while i<= N:
    if i == 1:
        j = 2
    else:
        j = 1
    while j <= i - 1:
        print(' ', end=(''))
        j = j + 1
    j = i
    while j <= N:
        print(j, end=(''))
        j = j + 1
    print()
    i = i + 1
i = 1
while i <= N - 1:
    j = N - 2
    while j >= i:
        print(' ', end=(''))
        j = j - 1
    a = N - i
    j = 0
    while j <= i:
        print(a, end=(''))
        j = j + 1
        a = a + 1
    print()
    i = i + 1
