Smallest and Largest Element in an array using Python

 

Here, in this page we will discuss the program to find the smallest and largest element in an array using python programming language. We will discuss different algorithms to find the smallest and largest element of the given input array.

Method Discussed are given below :

  • Method 1 : Using Iteration.
  • Method 2 : Using Sort() function.
  • Method 3 : Using max() and min() function

Method 1 :

  • Take a variable say mini to store the minimum element of the array and maxi to store the maximum element.
  • Set mini = arr[0] and maxi = arr[0]
  • Run a loop over the array
  • Check if(arr[i]<mini) then set mini = arr[i]
  • Also check if(arr[i]>maxi) then set maxi = arr[i]
  • After complete iteration print mini and maxi.
  •  

Method 1 : Code in Python

Run 
arr = [10, 89, 9, 56, 4, 80, 8]
mini = arr[0]
maxi = arr[0]

for i in range(len(arr)):
  if arr[i] < mini: mini = arr[i] 
  
if arr[i] > maxi: maxi = arr[i]

print (mini)
print (maxi)

Output :

4

89

Method 2 :

  • Sort the array using inbuilt sort()function
  • Minimum element is at index 0 and maximum is at index -1
  • So, print(arr[0])
  • And, print(arr[-1])
smallest and largest element in an array using python

Method 2 : Code in Python

Run 
arr = [10, 89, 9, 56, 4, 80, 8]
arr.sort()

print (arr[0])
print (arr[-1])

Output :

4

89

Method 3 :

  • Using inbuilt function min(arr) , it return minimum element of the array.
  • Similarly max(arr) return the maximum element of the array.

Method 3 : Code in Python

Run 
arr = [10, 89, 9, 56, 4, 80, 8]

print (min(arr))
print (max(arr))

Output :

4

89

    size=int(input(“enter the lentgh of array”))
    arr=[]
    for i in range(size):
    arr.append(int(input(“Enter the Values–>”)))
    arr.sort()
    print(“the smallest value”,min(arr),”the gretaes value”,max(arr))

    The written code will mislead students a lot please do change with something like this:
    n=int(input(“Enter number of elements:”))
    a=[int(i) for i in input(“Enter space seprated element:”).split()]
    s=set(a)
    ls=list(s)
    ls.sort()
    print(“Largest element=”,ls[-1])
    print(“Smallest element=”,ls[0])
