2D Array - DS

  • [deleted]     + 1 comment

    SImple Python solution: We need to initialize count to -64 as matrix will be always 6*6 and values must be -9<=x<=9. So if all values will be -9 in that case we will get -63 as max value. Pass all test cases

    def hourglassSum(arr):
    count = -64
    row = 0
    col = 0
    while row < 4 :
        temp = arr[row][col] + arr[row][col+1]+arr[row][col+2]+arr[row+1][col+1] + arr[row+2][col]+arr[row+2][col+1]+ arr[row+2][col+2]
        if temp > count:
            count = temp
        col +=1
        if col == 4:
            col = 0
            row +=1
    return count
