Python subjective question(recursion) for competitive exam (31)

Q1. Program of linear search using recursion.

def linearsearch(l,size,item):
    if(size<0):
        print("search unsucessful")
    elif(l[size]==item):
             print("search successful")
    else:
        linearsearch(l,size-1,item)   
l=[1,2,3,5,8,9,10,4,6,7]
item=int(input("enter item you search"))
linearsearch(l,len(l)-1,item)

Output

enter item you search90
search unsucessful
>>>

enter item you search1
search successful

Q2.Program of binary search using recursion.

import math
def binarysearch(li,f,l,item):
    mid=math.ceil((f+l)/2)
    if(f>l):
        print("search unsuccessful")
    elif(li[mid]==item):
        print("seach successful")
    elif(li[mid]>item):
        binarysearch(li,f,mid-1,item)
    else:
        binarysearch(li,mid+1,l,item)

l=[1,2,3,4,5,6,7,8,9,10]
item=int(input("enter item"))
binarysearch(l,0,len(l)-1,item)

>>> 
=== RESTART: C:/Users/Dell/AppData/Local/Programs/Python/Python37-32/ss.py ===
enter item7
seach successful
>>> 
=== RESTART: C:/Users/Dell/AppData/Local/Programs/Python/Python37-32/ss.py ===
enter item90
search unsuccessful

Q3.Program to find factorial using recursion.

def factorial(n):
    if(n==1):
        return(1)
    else:
        return(n*factorial(n-1))

n=int(input("enter number to get factorial"))
r=factorial(n)
print(r)

Output
>>> 
=== RESTART: C:/Users/Dell/AppData/Local/Programs/Python/Python37-32/ss.py ===
enter number to get factorial4

        print(n,end='')
n=10
printnumber(n)
