sys.setrecursionlimit(1<<64)

Line 3: OverflowError: Python int too large to convert to C long

max: 2**64-1, (1<<64) - 1

sys.setrecursionlimit(1<<31)

Line 3: OverflowError: signed integer is greater than maximum

signed integer should be -1<<31 ~ (1<<31) - 1, -2**31 ~ 2**31

how to map list of list?

#not right
class Solution:

    # @param {character[][]} matrix

    # @return {integer}

    def maximalRectangle(self, matrix):

        print matrix,range(len(matrix)), range(len(matrix[])),matrix[][]

        a=[]

        for i in range(len(matrix)):

            tmp = []

            for j in range(len(matrix[])):

                tmp.append((i,j))

            a.append(tmp)

        print a

        matrix = map(lambda x: int(matrix[x[]][x[]]), a)#range(len(matrix)), range(len(matrix[])))

        print matrix
