Split and Replace

Given three strings

inputString, separator and replaceString as inputs. Write a Python program to split the

inputString with the given separator and replace strings in the resultant array with the replaceString whose length is greater than 7.

input:

Javascript-is-amazing

-

programming

Output

• The output should be a single line containing an array with alternate numbers squared

Constraints

• Each value in the array must be a number

input:

[1,2,3,4,5]

Consider the 2021 puzzle, which is a lot like the 15-puzzle we talked about in class, but: (1) it’s played on a 4x5 board, (2) it has 20 tiles, so that there are no empty spaces on the board, (3) instead of moving a single tile into an open space, a move in this puzzle consists of either (a) sliding an entire row of tiles left or right, with the left- or right-most tile “wrapping around” to the other side of the board, or (b) sliding an entire column of the puzzle up or down, with the top- or bottom-most tile “wrapping around.” However, each given row or column can only be slid in a certain way: the first and third rows can only be slid left; the second and fourth rows can only be slid right; the first, third, and fifth columns can only be slid up; and the second and fourth columns can only be slid down. For example, here is a sequence of two moves on such a puzzle: 2 1 2 3 4 5 1 2 3 4 5 1 17 3 4 5 6 7 8 9 10 → 10 6 7 8 9 → 10 2 7 8 9 11 12 13 14 15 11 12 13 14 15 11 6 13 14 15 16 17 18 19 20 16 17 18 19 20 16 12 18 19 20 The goal of the puzzle is to find a short sequence of moves that restores the canonical configuration (on the left above) given an initial board configuration. We’ve provided skeleton code to get you started. You can run the skeleton code on the command line: python3 solver2021.py [input-board-filename] where input-board-filename is a text file containing a board configuration (we have provided an example). You’ll need to complete the function called solve(), which should return a list of valid moves, each of which is encoded as a letter L, R, U, or D for left, right, up, or down, respectively, and a row or column number (indexed beginning at 1). (For instance, the moves in the picture above would be R2 D2.) The initial code does not work correctly. Using this code as a starting point, implement a fast version, using A* search with a suitable heuristic function that guarantees finding a solution in as few moves as possible. Try to make your code as fast as possible even for difficult boards, although it is not necessarily possible to write code that will be able to quickly solve all puzzles. In addition to doing your own testing, it is important that you test your program on the SICE Linux servers to ensure that we will be able to run it and grade it accurately
