順序查找的遞歸實現，python順序查找的遞歸算法_Python實現查找算法

一.順序查找---O(n)

無序列表查找

def sequentialSearch(alist,item):

pos = 0

順序查找的遞歸實現、found = False

while pos < len(alist) and not found:

if alist[pos] == item:

found = True

else:

Python遞歸。pos = pos + 1

return found

list = [2,3,1,4,5,6,0]

print(sequentialSearch(list,5))

print(sequentialSearch(list,7))

java遞歸算法經典實例、有序列表查找

def ordersequentialSearch(alist,item):

pos = 0

found = False

stop = False

c語言遞歸。while pos < len(alist) and not found and not stop:

if alist[pos] == item:

found = True

else:

if alist[pos] > item:

遞歸、stop = True

else:

pos = pos + 1

return found

list = [1,2,3,4,5,6,7]

漢諾塔問題遞歸算法python。print(ordersequentialSearch(list,3))

print(ordersequentialSearch(list,9))

二.二分查找---O(log^n)

def binarySearch(alist,item):

first = 0

python遞歸求和。last = len(list) - 1

found = False

while first <= last and not found:

midpoint = (first + last) // 2

if alist[midpoint] == item:

遞歸算法經典實例。found = True

else:

if item < alist[midpoint]:

last = midpoint - 1

else:

python遞歸算法？first = midpoint + 1

return found

list = [0,1,2,3,4,5,6,7,8]

print(binarySearch(list,3))

print(binarySearch(list,10))

python遞歸程序的特點？遞歸實現二分查找

def binarySearchCur(alist,item):

if len(alist) == 0:

return False

else:

python 遞歸函數例子。midpoint = len(alist) // 2

if alist[midpoint] == item:

return True

else:

if item < alist[midpoint]:

遞歸算法1加到100、return binarySearchCur(alist[:midpoint],item)

else:

print(alist[midpoint+1:])

return binarySearchCur(alist[midpoint+1:],item)

def sequentialSearch(alist,item):pos = 0found = False
