Java BigDecimal

Problem Statement :

Java's BigDecimal class can handle arbitrary-precision signed decimal numbers. Let's test your knowledge of them!

Given an array, s, of n 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 .1 is printed as .1, and 0.1 is printed as 0.1. If two numbers represent numerically equivalent values (e.g., .1=0.1), 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's elements according to the instructions above.

Input Format

The first line consists of a single integer, , denoting the number of integer strings.
Each line i of the n subsequent lines contains a real number denoting the value of si.


  Each si has at most 300 digits.

Output Format

Locked stub code in the editor will print the contents of array s to stdout. You are only responsible for reordering the array's elements.

                            Solution in C :

import java.math.BigDecimal;
import java.util.*;
class Solution {
    public static void main(String []args){
        Scanner sc = new Scanner(;
        int n = sc.nextInt();
        String []s = new String[n+2];
        for(int i = 0;i < n;i++){
            s[i] =;

        for(int i = 0;i<n;i++){
            BigDecimal max = new BigDecimal(s[i]);
            int idx = i;
            for(int j = i+1;j<n;j++)
                BigDecimal curr = new BigDecimal(s[j]);
                if(curr.compareTo(max) == 1){
            String temp = s[i];
            s[i] = s[idx];
            s[idx] = temp;

        for(int i = 0;i<n;i++){

Delete duplicate-value nodes from a sorted linked list

This challenge is part of a tutorial track by MyCodeSchool You are given the pointer to the head node of a sorted linked list, where the data in the nodes is in ascending order. Delete nodes and return a sorted list with each distinct value in the original list. The given head pointer may be null indicating that the list is empty.

Cycle Detection

A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0. Example head refers 1 -> 2 -> 3 -> NUL The numbers shown are the node numbers, not their data values. There is no cycle in this list so return 0. head refer

Find Merge Point of Two Lists

This challenge is part of a tutorial track by MyCodeSchool Given pointers to the head nodes of 2 linked lists that merge together at some point, find the node where the two lists merge. The merge point is where both lists point to the same node, i.e. they reference the same memory location. It is guaranteed that the two head nodes will be different, and neither will be NULL.
