array-2d

You are given a 2D array. An hourglass in an array is a portion shaped like this: a b c d e f g For example, if we create an hourglass using the number 1 within an array full of zeros, it may look like this: 1 1 1 0 0 0 0 1 0 0 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Actually, there are many hourglasses in the array above. The three leftmost hourglasses are the following: 1 1 1 1 1 0 1 0 0 1 0 0 1 1 1 1 1 0 1 0 0 The sum of an hourglass is the sum of all the numbers within it. The sum for the hourglasses above are 7, 4, and 2, respectively. In this problem you have to print the largest sum among all the hourglasses in the array. Input Format There will be exactly lines, each containing integers seperated by spaces. Each integer will be between and inclusive. Output Format Print the answer to this problem on a single line. Sample Input 1 1 1 0 0 0 0 1 0 0 0 0 1 1 1 0 0 0 0 0 2 4 4 0 0 0 0 2 0 0 0 0 1 2 4 0 Sample Output 19 Explanation The hourglass which has the largest sum is: 2 4 4 2 1 2 4

arraylist

Sometimes it's better to use dynamic size arrays. Java's Arraylist can provide you this feature. Try to solve this problem using Arraylist. You are given lines. In each line there are zero or more integers. You need to answer a few queries where you need to tell the number located in position of line. Take your input from System.in. Input Format The first line has an integer . In each of the next lines there will be an integer denoting number of integers on that line and then there will be space-separated integers. In the next line there will be an integer denoting number of queries. Each query will consist of two integers and . Constraints Each number will fit in signed integer. Total number of integers in lines will not cross . Output Format In each line, output the number located in position of line. If there is no such position, just print "ERROR!" Sample Input 5 5 41 77 74 22 44 1 12 4 37 34 36 52 0 3 20 22 33 5 1 3 3 4 3 1 4 3 5 5 Sample Output 74 52 37 ERROR! ERROR! Explanation The diagram below explains the queries: image

bigdecimal-sort

Java's BigDecimal class can handle arbitrary-precision signed decimal numbers. Let's test your knowledge of them! Given an array, , of real number strings, sort them in descending order — but wait, there's more! Each number must be printed in the exact same format as it was read from stdin, meaning that is printed as , and is printed as . If two numbers represent numerically equivalent values (e.g., ), then they must be listed in the same order as they were received as input). Complete the code in the unlocked section of the editor below. You must rearrange array 's elements according to the instructions above.
