In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven a dictionary, we need to find the three highest valued values and display them.Approach 1 − Using the collections module ( Counter function )Example Live Demofrom collections import Counter # Initial Dictionary my_dict = {'t': 3, 'u': 4, 't': 6, 'o': 5, 'r': 21} k = Counter(my_dict) # Finding 3 highest values high = k.most_common(3) print("Dictionary with 3 highest values:") print("Keys: Values") for i in high: print(i[0], " :", i[1], " ")OutputDictionary with 3 highest values: Keys: Values r : 21 t ...

In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven list input, we need to find the largest numbers in the given list .Here we will discuss two approachesUsing sorting techniquesUsing built-in max() functionApproach 1 − Using built-in sort() functionExample Live Demolist1 = [18, 65, 78, 89, 90] list1.sort() # main print("Largest element is:", list1[-1])OutputLargest element is: 90Approach 2 − Using built-in max() functionExample Live Demolist1 = [18, 65, 78, 89, 90] # main print("Largest element is:",max(list1))OutputLargest element is: 90ConclusionIn this article, we learnt about the approach to find largest number in a list.
Following is the Java program for Longest Common Subsequence −Example Live Demopublic class Demo{ int subseq(char[] a, char[] b, int a_len, int b_len){ int my_arr[][] = new int[a_len + 1][b_len + 1]; for (int i = 0; i
Following is the Java program to print Triangle pattern −Example Live Demoimport java.util.*; public class Demo{ public static void main(String[] args){ Scanner my_scan = new Scanner(System.in); System.out.println("Enter the number of rows which needs to be printed"); int my_row = my_scan.nextInt(); for (int i = 1; i = i; j--){ System.out.print(" "); } for (int j = 1; j
Following is the Java program to print integer between Strings −Example Live Demopublic class Demo{ public static void main(String[] args){ System.out.println("The equals symbol is present between two integer values "); System.out.println(45+5 + "=" +(56+11)); System.out.println(45+5 + " equals symbol " +(56+11)); } }OutputThe equals symbol is present between two integer values 50=67 50 equals symbol 67A class named Demo contains the main function that prints integer values between two strings.
Following is the code to rename multiple files using Java −Exampleimport java.io.File; import java.io.IOException; public class Demo{ public static void main(String[] argv) throws IOException{ String path_to_folder = "path\to\folder\where\multiple\files\are\present"; File my_folder = new File(path_to_folder); File[] array_file = my_folder.listFiles(); for (int i = 0; i < array_file.length; i++){ if (array_file[i].isFile()){ File my_file = new File(path_to_folder + "\" + array_file[i].getName()); String long_file_name = array_file[i].getName(); String[] my_token = long_file_name.split("\s"); ...

Following is the code to clear screen using Java −Example Live Demopublic class Demo{ public static void main(String[] args){ System.out.print("\033[H\033[2J"); System.out.flush(); } }OutputThe screen would be clearedA class named Demo contains the main function. Here, the ANSI escape code is written, that clears the screen. The flush function resets the cursor to the top of the window screen.
Suppose we want to write a class called RecentCounter to count recent requests. This class has only one method: ping(t), where t is representing some time in milliseconds. This will return the number of pings that have been made from 3000 milliseconds ago until now. Any ping with time in [t - 3000, t] will count, including the current ping. And it is guaranteed that every call to ping uses a strictly larger value of t than before.So, if the input is like Call ping four times ping(1), ping(100), ping(3001), ping(3002), then the output will be 1, 2, 3, 3 ...

Suppose we have a deck of cards, each card has an integer written on it. We have to check whether we can choose X >= 2 such that it is possible to split the entire deck into 1 or more groups of cards, where the following condition satisfies: Each group has exactly X number of cards. All of the cards in each group have the same number.So, if the input is like deck = [1, 2, 3, 4, 4, 3, 2, 1], then the output will be True, as possible partitions are [1, 1], [2, 2], [3, 3], [4, 4].To ...
