Title Description

title

Analyze the amount of data

• 1 <= matrix.length, matrix[0].length <= 200 ： 1 0 8 / 1 0 2 = 1 0 6 , ( 1 0 2 ) 3 = 1 0 6 10^8 / 10^2 = 10^6,(10^2)^3 = 10^6 108/102=106,(102)3=106, So the maximum time complexity of the algorithm is O ( N 3 ) O(N^3) O(N3), It can be used dp To do it
