Given a grid of size n x len filled with lowercase characters. We can swap two adjacent characters in the same row and column. Now we have to check whether it is possible to arrange in such a order that every row and every column in the grid is lexicographically sorted.
Input : abcde fghij olmkn trpqs xywuv Output : Yes Explanation : The grid can be rearranged as abcde fghij klmno pqrst uvwxy
The idea to do the above problem is really simple we can simply sort the characters in the same row and then just
check column vise if the new grid is sorted column vise or not. Please not that sorting is possible with adjacent swaps (Bubble sort for example does only adjacent swaps)
The implementation of the above idea is given below.

- Sort Matrix in alternating ascending and descending order rowwise
- Meta Strings (Check if two strings can become same after a swap in one string)
- Minimum swaps to reach permuted array with at most 2 positions left swaps allowed
- Check if cells numbered 1 to K in a grid can be connected after removal of atmost one blocked cell
- Largest number not greater than N which can become prime after rearranging its digits
- Find if array can be sorted by swaps limited to multiples of k
- Check if a string can become empty by recursively deleting a given sub-string
- Check if frequency of all characters can become same by one removal
- String slicing in Python to check if a string can become empty by recursive deletion
- Generate lexicographically smallest string of 0, 1 and 2 with adjacent swaps allowed
- Number of swaps to sort when only adjacent swapping allowed
- Generate permutations with only adjacent swaps allowed
- Minimum adjacent swaps required to Sort Binary array
- Minimum number of adjacent swaps to convert a string into its given anagram
- Minimize count of adjacent row swaps to convert given Matrix to a Lower Triangular Matrix
- Check if the robot is within the bounds of the grid after given moves
- Count of strings that become equal to one of the two strings after one removal
- Check if the array can be sorted only if the elements on given positions can be swapped
- Maximum sum in a 2 x n grid such that no two elements are adjacent
- Minimum product in a grid of adjacent elements
