    You say in input description n lines of string of length n.

    But in the sample testcase itself you give input with n = 4 but string length as 3.

    Either correct the Testcases of problem description.

    Before redeeming any promo code on CSGO500, I check the terms: Is there a deposit needed? Are there playthrough requirements? When I found TOP100LIST on https://cyber-sport.io/csgo500-promo-code, it clearly explained all that. That’s why it worked for me without surprises. I didn’t need to gamble a huge amount to unlock the bonus. Sites like Cyber-Sport.io take the guesswork out of promo codes, making sure users know exactly what they’re getting into before they click “redeem.”

    My solution, it might complex

    def gridChallenge(grid):
    # Sort each row
    for idx in range(len(grid)):
        strList = list(grid[idx])
        strList.sort()
        grid[idx] = "".join(strList)
    # Join all grid list to a single string
    strJoin = "".join(grid)
    gLength = len(grid)
		# Create the column list based on grid length
    reverseGrid = [0] * len(grid)
    for i in range(len(strJoin)):
		    # get the ascii code
        curr = ord(strJoin[i])
				# Get the saved grid ascii code based on index % length
        prev = reverseGrid[i % gLength]
        diff = curr - prev
				# if the diff < 0, means current ascii value less than previous, which means it's not in order
        if diff < 0:
            return "NO"

        reverseGrid[i % gLength] = curr
    return "YES"

    python easy solution: 

    def gridChallenge(grid):
    # Sort each row
    sorted_grid = [''.join(sorted(row)) for row in grid]
    
    # Zip to get columns
    for col in zip(*sorted_grid):
        if list(col) != sorted(col):
            return "NO"
    return "YES"

    It's NOT square matrix. Problem Description is Bad
