Smallest K digit number that divisible by X is found using the formula by checking divisible by X. The formula works in the following way −Compute minimum K digit number [min] for example: 10/100/1000 etc.Now find if min is divisible by X. if yes, then this is the answer.If not, then min+X - ([min+X]%k) is the answer.Example#include #include using namespace std; int main() {    int X = 83;    int K = 5;    cout

Power function is calculated using the times multiple i.e. 5n is 5*5*5… n times. For this function, to work properly without using multiplication(*) and division(/) operators we will use nested loops that add the numbers n number of time.Example#include using namespace std; int main() {    int a= 4 , b = 2;    if (b == 0)       cout

The sum of squares of the first n even numbers means that, we first find the square and add all them to give the sum.There are two methods to find the sum of squares of the first n even numberUsing LoopsWe can use loops to iterate from 1 to n increase number by 1 each time find the square and add it to the sum variable −Example#include using namespace std; int main() {    int sum = 0, n =12;    for (int i = 1; i

Finding the number of vowels in a string using pointers need you to understand string, vowels and how to use pointer with string.String is an array of characters. And vowels are characters from the set {a, e, i, o, u}. Pointer is a variable that stores the value of memory location on a variable.To find the number of vowels in a string. We will traverse the string and then compare each character with vowels and if it is equal then it increase a counter otherwise not.Condition of the below code is that it requires a string that has all lowercase ...

This program is used to find all the even factors and calculate the sum of these even factors and display it as output.Example −Input : 30 Even dividers : 2+6+10+30 = 48 Output : 48For this, we will find all the factors. Find the even of them and find the sum, Else, we will use the formula to find the sum of factors using the prime factors, Sum of divisors = (1 + d11 + d12 ... d1a1) *(1 + d21 + d22 ... d2a2) *...........................* (1 + dk1 + dk2 ... dkak) Here di = prime factors ; ai ...

A sequence of characters or a linear array of character is known as String. Its declaration is same as define other arrays.Length of array is the number of characters in the String. There are many in-built method and other methods to find the length of string. Here, we are discussing 5 different methods to find the length of a string in C++.1) Using the strlen() method of C − This function returns an integer value of the C. For this you need to pass the string in the form of character array.PROGRAM TO ILLUSTRATE THE USE OF strlen() METHOD#include ... Read More

With the increase in popularity of the Python programming language, more and more features are becoming available for Python developers. Usage of these features helps us to write efficient code. In this article, we will see 10 Python tricks that are very frequently used. Reversing a List We can reverse a given list by using the reverse() function. It returns the elements of the current list in reverse order. It works with both numeric and string datatypes. Example Let's see how to use the reverse() function in your Python program to reverse a list of strings: List = ["Shriya", "Lavina", "Sampreeti" ... Read More

In python the print statement adds a new line character by default. So when we have multiple print statements the output from each of them is printed in multiple lines as you can see in the example below. Our goal is to print them in a single line and use some special parameters to the print function to achieve that.Normal Print()The below example prints multiple statements with new lines in each of them.Exampleprint("Apple") print("Mango") print("Banana")OutputRunning the above code gives us the following result −Apple Mango BananaUsing end ParameterWe can use the end parameter to use a specific character at the ...

Google offers many python packages which minimize the effort to write python code to get data from google services. One such package is google images download. It takes in the key words as parameters and locates the images with those keywords.ExampleIn the below example we limit the number of images to 5 and also allow the program to print the urls from where the files were generated.from google_images_download import google_images_download #instantiate the class response = google_images_download.googleimagesdownload() arguments = {"keywords":"lilly, hills", "limit":5, "print_urls":True} paths = response.download(arguments) #print complete paths to the downloaded images print(paths)OutputRunning the above code gives us the following ...
