interesting def


Interesting  ~

>>> i =5
>>>
>>> def f(arg=i):
print(arg)

>>> i =7
>>> f()

guess what number??

the result is 5


List Type

I think Python is very simple to learn
simple to understand
simple to code...

there are many advantage if I use this language.

Now I start to learn list

Make List:
squares = [1,2,3,4,5]

Add List:
squares.append(6)

Copy List:
sqaures[:]

Range List:
sqaures[0:2]

Clear List:
sqaures = []

Problem 84

Before solving this problem
I thought lost of time. because. It request to me that I had to make monopoly rules and playing it to make statistic.

Anyway I made up~ never give up~!



What I learned from this problem is that statistics are very strong~!!!!!!

Project euler 81~ 83 : BFS(Breadth-First-Search)

These questions were very easy to me~!

Because I studied graph algorithm very hard and posted on my blogger.

https://projecteuler.net/problem=83


# List #

1. BFS(Breadth-First-Search),
2. DFS(Depth-First-Search),
3. Prim algorithm,
4. Union Find algorithm,
5. Kruskal algorithm,
6. Topology algorithm,
7. dijkstra's algorithm



What I had to do was thinking about how to efficiently access good solution by past times.

I choosed BFS login with Queue and find all possible path.

condition
up case : if (sum[po.y - 1][po.x] > curSum + val[po.y - 1][po.x]) {
  sum[po.y - 1][po.x] = curSum + val[po.y - 1][po.x];
  queue.add(new Position(po.x, po.y - 1));
        }

right down, left ...

Problem 80

I solve this problem by using 57 problem, 64, 65
I think problem is getting harder than before and....
because of time and difficulty, It seem that I want to stop it.
but I wil do it continuously

I started Just Python

My first Language was Java
Second is javascript,
third is c
fourth is Python which I'm trying to learn ~!

Compare to java.
this is amazing and very simple

ex)
>>> 3 * 'abc' + 'de'
'abcabcabcde'

>>> word = 'Python'
>>> word[0:2]
'Py'

Very Very Interesting..

I will use it more and more
