2639. Find the Width of Columns of a Grid

Leetcode Solutions

Iterative Maximum Column Width Calculation

  1. Initialize an array widths with the size equal to the number of columns in grid, filled with zeros.
  2. Iterate over each column j of the grid.
  3. For each column, iterate over each row i.
  4. Calculate the width of the current element grid[i][j] by converting it to a string and taking the length of the string.
  5. If the current element is negative, increment the width by 1.
  6. Update the maximum width for the column j by comparing the current width with the existing value in widths[j].
  7. After iterating through all rows, continue to the next column.
  8. Return the widths array after processing all columns.
