Codewars supports 21 programming languages overall, plus the support of another 17 less popular ones is currently in beta. Codewars For solving tasks and completing challenges users get points. Interestingly, the size of the reward depends on how elegant and efficient the suggested solution was.
Another interesting feature of this platform is that it allows you to see different options to solve the challenges, suggested by other users, allowing you to learn from more experienced programmers.

Do we need to return anything? Print a message asking the user for a row and use the Scanner to get their input, storing it in a variable called row ; repeat this for col. If the user enters a row and col that is out of bounds or a row and col that already has an x or o on it, then we want to ask the user to re-enter a row and col. We can use a loop to do this!
Outside of the while loop, we know that we have a valid row and col. We can get the position on the board by doing board[row][col]. Now we can set this position to be equal to the char of the player, which we stored in the variable c.
Inside the for loop, we can use a conditional to check if board[i][0] equals board[i][1] and if board[i][1] equals board[i][2]. If that is all true, then we can return the value of board[i][0]. There are two diagonals on the board that we have to check. We can use two if statements to check the two diagonals, similar to the if statements we used for rows and columns. If we reach the end of our function, that means that nobody has won.
Here, we can just return a space. Tic tac toe ends in a tie if nobody has won and the board is full. We already have checked if someone has won. Now we just need to check if the board is full. Remember, an empty spot is a dash.
Once we finish going through the nested for loops and find that no position on the board equals a dash, then we know that the board is full so we can return true. We can create a boolean called gameEnded and initially set it to false. Inside the if statement where we check if a player has won or if it is a tie, we can set gameEnded to true. We can make a while loop, with its condition simply being gameEnded , so that the program keeps asking a player to enter a row and col until there is a winner or a tie.
How can we fix this? After the while loop is over, we can draw the board a final time so that both players can see the final state of the board. Built the project above? We'd love to see it!
