Python: Finding largest continuous sum in a list/array

 Problem Statement:

Given a list of integers (both positive and negative) find the largest continuous sum.

e.g. 

Input:

list1 = [1, 2, -1, 3, 4, 10, 10, -10, -1]

Output: 29

Solution:

def largest_cont_sum(list1):

    max_sum = current_sum = 0

    

    if len(list1) == 0:

        return "There is no any element in the List"

    

    for num in list1:

        current_sum = max(current_sum + num, num)

        max_sum = max(current_sum, max_sum)

    

    return max_sum

list1 = [1,2,-1,3,4,10,10,-10,-1]

print("The Largest continuous sum is:",largest_cont_sum(list1))

Output: The Largest continuous sum is: 29

Python: Find the missing element

 Problem Statement: Consider array/list of non-negative integers. The second array/list is formed by shuffling the elements of the first array/list and deleting a random element. Given these two arrays/lists, find which element is missing in second array.

e.g.

list1 = [1, 2, 3, 4, 5, 6]

list2 = [2, 5, 4, 6, 3]

here missing element is 1.

Solution:

def missing_ele(list1, list2):

    list1.sort()

    list2.sort()

    for num1, num2 in zip(list1, list2):

        if num1 != num2:

            return num1

    return list1[-1]

list1 = [1, 2, 3, 4, 5, 6]

list2 = [2, 4, 6, 3, 5]

print("Missing element is: ", missing_ele(list1, list2))

Output: Missing element is: 1

Here, I have simulated a Monostable Multivibrator in Proteus design suite.

Python: Addition, Subtraction, Multiplication and Division using function

Program: 

#Addition function

def addition(a,b):

    c=a+b

    print("Addition= ",c)

print("Enter two numbers")

#Subtraction function

def subtraction(a,b):

    c=a-b

    print("Subtraction= ",c)

#Multiplication function

def multiplication(a,b):

    c=a*b

    print("Multiplication= ",c)

#Division function

def division(a,b):

    c=a/b

    print("Division= ",c)

a=float(input())

b=float(input())

addition(a,b)

subtraction(a,b)

multiplication(a,b)

division(a,b)

Output:

Enter two numbers

Addition=  12.0

Subtraction=  4.0

Multiplication=  32.0

Division=  2.0

Python: Addition of two numbers using function

Below is a simple addition program demonstrated using function addition. This program shows you how to use function in Python 

def addition(a,b): #This is funtion definitation

    c=a+b

    print("Addition = {}".format(c))

print("Enter two numbers to be added")

a=int(input())

b=int(input())

addition(a,b) #call the function addition() by passing two numbers a & b

Text in green are comments

Output:

Enter two numbers to be added

341

12

Addition = 353

Program for addition of two number using Python

 This is a simple program for addition of two numbers using Python.

Program takes two numbers as input from the user and prints the sum as output.

#Simple Program for addition of two number without using function

print("Enter two numbers to be added")

#int can have numbers in the range -2147483648 through 2147483647

a=int(input()) #takes first number as input from user

b=int(input()) #takes second number as input from user

c=a+b          #adds two numbers a & b and saves to c

print("Addition of numbers {} and {} is {}".format(a,b,c))

Text in green color shows the comments

Output:

Enter two numbers to be added

123

123

Addition of numbers 123 and 123 is 246
