* 寫下如何完成 Big File 這題 CTF
在終端機輸入 cat bigfile | grep CTF
CTF後面的字串即是答案
* 簡述 mv ./a ./b 這行指令意義
將檔案a的內容複製到b檔案裡面後，刪除a檔案
* 使用 Python 印出菱形並截圖4顆*、5顆*、6顆* 輸出結果-1
4顆、5顆、6顆:

def make(rows):
    for i in range(0,rows):
        for j in range(0,rows-(i+1)):
            print " ",
            j +=1
        for k in range(0,(rows-1)*i+1):
            if k>=2*i+1 :
                print " ",
            else:
                print "*",
            k += 1
        print " "
    i += 1
    for i in range(0,rows-1):
        for j in range(0,i+1):
            print " ",
            j += 1
        for k in range(0,2*((rows-1)-i)-1):
            print "*",
            k += 1
        print "  "
    i += 1
make(4)
print "\n"
make(5)
print "\n"
make(6)


* 使用 Python 印出並截圖4顆*、5顆*、6顆 輸出結果-2

def make(star):
  for i in range(0,star):
    for j in range(0,star-i):
      print "*",
    print""
    i += 1
  for i in range(1,star+1):
    for j in range(0,10):
      if(9-j>=i):
        print " ",
      else:
       print "*",
    print""
    i += 1
make(4)
make(5)
make(6)


* 寫一個 Python Function

for i in range(0,10):
  a=input("input:")
  d=a/100
  e=(a%100)/10
  f=(a%100)%10
  if(d==0):
    print(e),
    print("*10+"),
    print(f),
    print("*1")
  elif(e==0):
    print (d),
    print("*100+"),
    print(f),
    print("*1")
  elif(f==0):
    print (d),
    print("*100+"),
    print(e),
    print("*10+"),
  elif(d==0 and e==0):
    print(f),
    print("*1")
  elif(d==0 and f==0):
    print(e),
    print("*10+"),
  elif(e==0 and f==0):
    print (d),
    print("*100+"),
  else:
    print (d),
    print("*100+"),
    print(e),
    print("*10+"),
    print(f),
    print("*1")
i+=1
