so here is a problem :
Okabe needs to renovate the Future Gadget Laboratory after he tried doing some crazy experiments! The lab is represented as an n by n square grid of integers. A good lab is defined as a lab in which every number not equal to 1 can be expressed as the sum of a number in the same row and a number in the same column. In other words, for every x, y such that 1 ≤ x, y ≤ n and ax, y ≠ 1, there should exist two indices s and t so that ax, y = ax, s + at, y, where ai, j denotes the integer in i-th row and j-th column.
Help Okabe determine whether a given lab is good!
The first line of input contains the integer n (1 ≤ n ≤ 50) — the size of the lab.
The next n lines contain n space-separated integers denoting a row of the grid. The j-th integer in the i-th row is ai, j (1 ≤ ai, j ≤ 105).
Print "Yes" if the given lab is good and "No" otherwise.
You can output each letter in upper or lower case.
1 1 2
2 3 1
6 4 1
here is my code:
from random import randint x = int(input("number: ")) board =  for a in range(x): row =  for b in range(x): row.append(str(randint(2,3))) board.append(row) def boardy(board): for x in board: print(" ".join(x)) boardy(board) q=int in range(0,x) r=int in range(0,x) e=int in range(0,x) o=int in range(0,x) if board[q][r]==board[q][e]+board[o][r]: print(True) else: print( False)
please help me with answer , i have been stuck in this problem sice yesterday and i am loosing motivation to continue coding as i cant move forward.. thanking you in anticipation
