Hackerrank - Big Sorting

 Consider an array of numeric strings where each string is a positive number with anywhere from  to  digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array.

Example

Return the array ['1', '3', '150', '200'].

Function Description

Complete the bigSorting function in the editor below.

bigSorting has the following parameter(s):

  • string unsorted[n]: an unsorted array of integers as strings

Returns

  • string[n]: the array sorted in numerical order

Input Format

The first line contains an integer, , the number of strings in .
Each of the  subsequent lines contains an integer string, .

Constraints

  • Each string is guaranteed to represent a positive integer.
  • There will be no leading zeros.
  • The total number of digits across all strings in  is between  and  (inclusive).

Explanation 0

The initial array of strings is . When we order each string by the real-world integer value it represents, we get:

We then print each value on a new line, from smallest to largest.

Hackerrank - Quicksort 2 - Sorting

Image
     Problem Submissions Leaderboard Discussions In the previous challenge, you wrote a partition method to split an array into two sub-arrays, one containing smaller elements and one containing larger elements than a given number. This means you 'sorted' half the array with respect to the other half. Can you repeatedly use partition to sort an entire array? Guideline In Insertion Sort, you simply went through each element in order and inserted it into a sorted sub-array. In this challenge, you cannot focus on one element at a time, but instead must deal with whole sub-arrays, with a strategy known as "divide and conquer". When partition is called on an array, two parts of the array get 'sorted' with respect to each other. If partition is then called on each sub-array, the array will now be split into four parts. This process can be repeated until the sub-arrays are small. Notice that when partition is called on just one of the numbers, the...

Hackerrank - Day of the Programmer

  Marie invented a   Time Machine   and wants to test it by time-traveling to visit Russia on the   Day of the Programmer   (the 256th day of the year) during a year in the inclusive range from 1700 to 2700. From 1700 to 1917, Russia's official calendar was the  Julian calendar ; since 1919 they used the  Gregorian calendar  system. The transition from the Julian to Gregorian calendar system occurred in 1918, when the next day after January 31st was February 14th. This means that in 1918, February 14th was the 32nd day of the year in Russia. In both calendar systems, February is the only month with a variable amount of days; it has 29 days during a  leap year , and 28 days during all other years. In the Julian calendar, leap years are divisible by 4; in the Gregorian calendar, leap years are either of the following: Divisible by 400. Divisible by 4 and  not  divisible by 100. Given a year,  , find the date of the 256th day of t...

Hackerrank - UNIQUE ARMSTRONG NUMBER

Consider a non-empty array Inarr of unique elements such as satisfies the following condition 0 Starting from the leftmost element in inarr, for each element Form all possible numbers by concatenating pair of elements in inarr such that the second element of the pair appears after the first element in inarr. From the numbers formed, find and add the unique Armstrong numbers) outarr in the order of occurrence of elements in inarr. If two pairs have the same first number, then consider the order of occurrence of second elements in the pairs An Armstrong number is equal the sum of its own digits each raised to the power of the number of digits in the number If there is no Armstrong number found, print-1 as output Input Format First line contains inarr, with the elements separated by ‘,’ (comma) Constraints Read the inputs from the standard input stream Output Format Print outarr, with the elements separated by ',' (comma) to the standard output stream Sample Input 0 15,3,1,70,53,7...
