To find the maximum and minimum element’s position in a list, the Java program is as follows −Example Live Demoimport java.util.*; import java.util.Arrays; import java.util.Collections; public class Demo{ public static int index_val(int my_arr[], int t){ if (my_arr == null){ return -1; } int len = my_arr.length; int i = 0; while (i < len){ if (my_arr[i] == t){ return i; } else { ...

To iterate over a Stream with Indices in Java 8, the code is as follows −Example Live Demoimport java.util.stream.IntStream; import java.util.*; import java.util.concurrent.atomic.AtomicInteger; public class Demo{ public static void main(String[] args){ String[] my_array = { "T", "h", "i", "s", "s", "a", "m", "p", "l", "e" }; AtomicInteger my_index = new AtomicInteger(); System.out.println("The elements in the string array are :"); Arrays.stream(my_array).map(str -> my_index.getAndIncrement() + " -> " + str).forEach(System.out::println); } }OutputThe elements in the string array are : 0 -> T 1 -> h 2 -> i 3 ...

To sort words of sentence in ascending order, the Java code is as follows −Example Live Demoimport java.util.*; public class Demo{ static void sort_elements(String []my_str, int n){ for (int i=1 ;i= 0 && temp.length() < my_str[j].length()){ my_str[j+1] = my_str[j]; j--; } my_str[j+1] = temp; } } public static void main(String args[]){ String []my_arr = {"This", "is", "a", "sample"}; int len = my_arr.length; sort_elements(my_arr,len); System.out.print("The sorted array is : "); for (int i=0; i
To split the Even and Odd elements into two different lists, the Java code is as follows −Example Live Demoimport java.util.Scanner; public class Demo{ public static void main(String[] args){ int n, j = 0, k = 0; Scanner s = new Scanner(System.in); System.out.println("Enter the number of elements required :"); n = s.nextInt(); int my_arr[] = new int[n]; int odd_vals[] = new int[n]; int even_vals[] = new int[n]; System.out.println("Enter the elements of the array(even and add numbers) ...

In this tutorial, we are going to write a program that flattens a list that contains sub-lists. Given number flatten the sublists until the given number index as parts. Let's see an example to understand it clearly.Inputlists = [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]] number = 2Output[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10]]Let's see the steps to solve the problem.Initialize the list and number.Initialize an empty list.Iterate over the list with range(0, len(lists), number.Get the sublists using slicing lists[i:number].Iterate over the sublists and append the resultant list to the result list.Print the result.Example# ...

In this tutorial, we are going to write a program that groups all the tuples from a list that have same element as a second element. Let's see an example to understand it clearly.Input[('Python', 'tutorialspoints'), ('Management', 'other'), ('Django', 'tutorialspoints'), ('React', 'tutorialspoints'), ('Social', 'other'), ('Business', 'other')]Output{'tutorialspoint': [('Python', 'tutorialspoints'), ('Django', 'tutorialspoints'), ('React', 'tutorialspoints')], 'other’: [('Management', 'other'), ('Social', 'other'), ('Business', 'other')]}We have to group the tuples from the list. Let's see the steps to solve the problem.Initiate a list with required tuples.Create an empty dictionary.Iterate through the list of tuples.Check if the second element of the tuple is already present in the dictionary ...
