Python - Calculate Money Change and Denomination

🐍 Python program to calculate change and denominations. The user enters the price and then the amount of money given. The program will figure out the change and the number of ones, twos, fives, tens, twenties, fifties, hundreds, two hundreds, and thousands to be returned.

Use dictionary data type.

Solution

def changecalculator(bill, received):
    if received > bill:

        change_dic = {'thousand' : 0, 'fivehundred' : 0, 'twohundred' : 0, 'hundred' : 0, 'fifty' : 0, 'twenty' : 0, 'ten' : 0, 'five' : 0, 'two' : 0, 'one' : 0}

        changeof = received - bill
        rem = changeof
        print(f"Amount to be returned: {rem}")
        while rem > 0:
            if rem >= 1000:
                change_dic['thousand'] += rem//1000
                rem = rem%1000
                
            elif rem >= 500:
                change_dic['fivehundred'] += rem//500
                rem = rem%500
                
            elif rem >= 200:
                change_dic['twohundred'] += rem//200
                rem = rem%200
                
            elif rem >= 100:
                change_dic['hundred'] += rem//100
                rem = rem%100
                
            elif rem >= 50:
                change_dic['fifty'] += rem//50
                rem = rem%50
                
            elif rem >= 20:
                change_dic['twenty'] += rem//20
                rem = rem%20
                
            elif rem >= 10:
                change_dic['ten'] += rem//10
                rem = rem%10
                
            elif rem >= 5:
                change_dic['five'] += rem//5
                rem = rem%5
                
            elif rem >= 2:
                change_dic['two'] += rem//2
                rem = rem%2
                
            elif rem >= 1:
                change_dic['one'] += rem//1
                rem = rem%1
                
    return change_dic
    
if __name__ == '__main__':
    bill = int(input("Enter the bill amount: "))
    received = int(input("Enter the received amount: "))
    print(changecalculator(bill, received))

Python - List - Append, Count, Extend, Index, Insert, Pop, Remove, Reverse, Sort

🐍 Advance List List is widely used and it's functionalities are heavily useful. Append Adds one element at the end of the list. Syntax list1.append(value) Input l1 = [1, 2, 3] l1.append(4) l1 Output [1, 2, 3, 4] append can be used to add any datatype in a list. It can even add list inside list. Caution: Append does not return anything. It just appends the list. Count .count(value) counts the number of occurrences of an element in the list. Syntax list1.count(value) Input l1 = [1, 2, 3, 4, 3] l1.count(3) Output 2 It returns 0 if the value is not found in the list. Extend .count(value) counts the number of occurrences of an element in the list. Syntax list1.extend(list) Input l1 = [1, 2, 3] l1.extend([4, 5]) Output [1, 2, 3, 4, 5] If we use append, entire list will be added to the first list like one element. Extend, i nstead of considering a list as one element, it joins the two lists one after other. Append works in the following way. Input l1 = [1, 2, 3] l1.append([4, 5]) Output...

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

  Approach #1: Insert Into Sorted Structure [Accepted] Intuition Let's add flowers in the order they bloom. When each flower blooms, we check it's neighbors to see if they can satisfy the condition with the current flower. Algorithm We'll maintain  active , a sorted data structure containing every flower that has currently bloomed. When we add a flower to  active , we should check it's lower and higher neighbors. If some neighbor satisfies the condition, we know the condition occurred first on this day. Complexity Analysis Time Complexity (Java):  O(N \log N) O ( N lo g N ) , where  N N  is the length of  flowers . Every insertion and search is  O(\log N) O ( lo g N ) . Time Complexity (Python):  O(N^2) O ( N 2 ) . As above, except  list.insert  is  O(N) O ( N ) . Space Complexity:  O(N) O ( N ) , the size of  active .
