Diagonal Difference of a 2D matrix












0












$begingroup$


How should I fix my code such that it will pass all corner cases not just some in HackerRank?



#!/bin/python3

import math
import os
import random
import re
import sys

# Complete the diagonalDifference function below.
def diagonalDifference(arr):
sum_diag1 = 0
sum_diag2 = 0
arr_2d =
print(arr)

for i in range(len(arr)):
for j in range(len(arr)):
if i==j:
sum_diag1 += arr[i][j]
elif i+j == (len(arr)) - 1:
sum_diag2 += arr[i][j]
print(arr[i][j])


return abs(sum_diag1 - sum_diag2)

if __name__ == '__main__':
fptr = open(os.environ['OUTPUT_PATH'], 'w')

n = int(input())

arr =

for _ in range(n):
arr.append(list(map(int, input().rstrip().split())))

result = diagonalDifference(arr)

fptr.write(str(result) + 'n')

fptr.close()

    Do you feel your code doesn’t work in certain “corner cases”? If so, you shouldn’t post it here, because non-working code is not appropriate for Code Review.
