    Problem and tests are not consistent, the problem states square grids but the test have non square grids.

    Scala Solution

    def gridChallenge(grid: Array[String]): String = {
    // Write your code here
    val sortedGrid = grid.map(row => row.sorted)
    val n = sortedGrid.length
    val m = sortedGrid(0).length
    for (col <- 0 until m) {
    for (row <- 0 until n - 1) {
      if (sortedGrid(row)(col) > sortedGrid(row + 1)(col)) {
        return "NO"
      }
    }
  }

  "YES"


    }

    I had to assume column length can differ from number of strings/rows/n;

    int cols = grid[0].Length;

    Using JS, I couldn't get test case 10 to work.

    It is too large for a custom input to test and doing it manually I got pretty deep into the test case file and was passing all the test cases,

    I passed all other test cases...and got it to work with Python, so yay...

    Not to mention the lies about the 'n' variable in the description.

    Overall, this was a great problem!

    Python3

    def gridChallenge(grid):
    columns = [0] * len(grid[0])
    for index in range(len(grid)):
        row = [ord(c) for c in grid[index]]
        row.sort()        
        for c in range(len(row)):
            if columns[c] > row[c]:
                return 'NO'
            columns[c] = row[c]
    return 'YES'``
