it helps some times The minimum number of moves is always XBXA+YBYA and we can do it always with only one turn. Example: move from (1,2) to (4,6): code :
3 moves right: 1500
1 turn: 100
4 moves down: 2000

3600

Finding a path through a checkerboard which is closest to a given cost

help you fix your problem No. If all the costs are integers, at each cell you need to store at most O(M) elements. So you need O(MN^2) memory. If the sum is >M you just ignore it. In this paper there is a mention of a pseudo polynomial algorithm to solve similar problem (exact cost). You can either use same algorithm multiple time with exact cost = M..1, or maybe read the algorithm and find a variation that solves your problem directly.

Finding a path travel cost closest to a given value

will help you I have been stuck on a problem recently. I have to find the cost of a path from the top left corner to the bottom right corner of a multidimensional array of integers. This path's cost has to be the greatest cost that does not go over a certain provided value. , You can update your memoize function to something like this: code :
def memoize (f):
memo = {}
def helper(*args):
if args not in memo:
memo[args] = f(*args)
return memo[args]
return helper
grid = [[0,2,5],[1,1,3],[2,1,1]]
answer(12, grid)
# 11
def fn(*args):
print(args)
fn(1,2,3)
(1, 2, 3)

I wish this help you I have determined the average subject cost as per the following: , I think that what you are trying to achieve is code :
SELECT *
FROM BOOK
JOIN
(
SELECT BOOK_SUBJECT,
AVG(BOOK_COST) AS AVGCOST,
MIN(BOOK_COST) AS MINCOST,
MAX(BOOK_COST) AS MAXCOST
FROM BOOK
GROUP BY BOOK_SUBJECT
) AS SUB USING (BOOK_SUBJECT)
ORDER BY BOOK_TITLE;
BOOK_SUBJECT BOOK_TITLE BOOK_COST
