Given an array of integers, find the largest number that can be constructed by concatenating all the elements of the given array.Input FormatFirst line of input contains T - number of test cases. Its followed by 2T lines. First line of each test case contains N - size of the array and the second line contains N integers - elements of the array.Constraints1 <= T <= 10001 <= N <= 10000 <= ar[i] <= 1000Output FormatFor each test case, print the largest number that can be constructed by concatenating all the elements of the given array, separated by newline.Sample Input 03849 73 58 30 72 44 78 23 469 9 57 60 240 4 Sample Output 078737258494430239696057440

Given two arrays (arr1[], arr2[]) of integers, display the largest number in arr1, where that element should not be present in arr2. If the constraint is not satisfied return 0.Variable Constraints:Size of the array <= 5;Array data type = integer.Input:Size of array 1Elements of array 1Size of array 2Elements of array 2Output:Largest element in array 1

You have been given an array 'A' of N integers. You need to find the maximum value of j - i subjected to the constraint of A[i] <= A[j], where ‘i’ and ‘j’ are the indices of the array.For example :If 'A' = {3, 5, 4, 1}then the output will be 2.Maximum value occurs for the pair (3, 4)Detailed explanation ( Input/output format, Notes, Images )Constraints:1 <= T <= 1001 <= N <= 10 ^ 4-10 ^ 5 <= A[i] <= 10 ^ 5Time limit: 1 sec.Sample Input 1:1934 8 10 3 2 80 30 33 1Sample Output 1:6Explanation:Maximum value occurs for the pair (8, 33)Sample Input 2:1109 2 3 4 5 6 7 8 18 0Sample Output 2:8Explanation:Maximum value occurs for the pair (9, 18)

You are given an array of 0's and 1's. Sort the array in ascending order and print it.Note: Solve using two-pointer technique.Input FormatFirst line of input contains T - the number of test cases. Its followed by 2T lines, the first line contains N - the size of the array.The second line contains the elements of the array.Constraints1 <= T <= 10001 <= N <= 10000 <= A[i] <= 1Output FormatFor each test case, sort the array in ascending order and print it on a new line.Sample Input 0250 1 1 0 161 1 1 1 1 0Sample Output 00 0 1 1 10 1 1 1 1 1Explanation 0

Given an array of unique integer elements, print all the subsets of the given array in lexicographical order.Input FormatThe first line of input contains T - the number of test cases. It's followed by 2T lines, the first line contains N - the size of the array and the second line contains the elements of the array.Output FormatFor each test case, print the subsets of the given array in lexicographical order, separated by new line. Print an extra newline between output of different test cases.Constraints1 <= T <= 1001 <= N <= 100 <= A[i] <= 100ExampleInput335 15 3 257 96 43 15 8 23 Output3 3 5 3 5 15 3 15 5 5 15 15 57 57 96 96 3 3 8 3 8 15 3 8 15 23 3 8 23 3 15 3 15 23 3 23 8 8 15 8 15 23 8 23 15 15 23 23
