Introduction To Algorithm

The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results. 

Advantages of Algorithms:

  • It is easy to understand.
  • Algorithm is a step-wise representation of a solution to a given problem.
  • In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

The Full Counting Sort– Hacker Rank Solution

Problem:

Use the counting sort to order a list of strings associated with integers. If two strings are associated with the same integer, they must be printed in their original order, i.e. your sorting algorithm should be stable. There is one other twist: strings in the first half of the array are to be replaced with the character - (dash, ascii 45 decimal).

Insertion Sort and the simple version of Quicksort are stable, but the faster in-place version of Quicksort is not since it scrambles around elements while sorting.

Design your counting sort to be stable.

Example

The first two strings are replaced with ‘-‘. Since the maximum associated integer is , set up a helper array with at least two empty arrays as elements. The following shows the insertions into an array of three empty arrays.

i	string	converted	list
0				[[],[],[]]
1 	a 	-		[[-],[],[]]
2	b	-		[[-],[-],[]]
3	c			[[-,c],[-],[]]
4	d			[[-,c],[-,d],[]]

The result is then printed:  .

Function Description

Complete the countSort function in the editor below. It should construct and print the sorted strings.

countSort has the following parameter(s):

  • string arr[n][2]: each arr[i] is comprised of two strings, x and s

Returns
– Print the finished array with each element separated by a single space.

Note: The first element of each , , must be cast as an integer to perform the sort.

Input Format

The first line contains , the number of integer/string pairs in the array .
Each of the next  contains  and , the integers (as strings) with their associated strings.

Constraints


 is even


 consists of characters in the range 

Output Format

Print the strings in their correct order, space-separated on one line.

Sample Input

20
0 ab
6 cd
0 ef
6 gh
4 ij
0 ab
6 cd
0 ef
6 gh
0 ij
4 that
3 be
0 to
1 be
5 question
1 or
2 not
4 is
2 to
4 the

Sample Output

- - - - - to be or not to be - that is the question - - - -

Explanation

The correct order is shown below. In the array at the bottom, strings from the first half of the original array were replaced with dashes.

0 ab
0 ef
0 ab
0 ef
0 ij
0 to
1 be
1 or
2 not
2 to
3 be
4 ij
4 that
4 is
4 the
5 question
6 cd
6 gh
6 cd
6 gh
sorted = [['-', '-', '-', '-', '-', 'to'], ['be', 'or'], ['not', 'to'], ['be'], ['-', 'that', 'is', 'the'], ['question'], ['-', '-', '-', '-'], [], [], [], []]

  1. Now for the economics lesson that everyone knows. Price is a function of supply and demand. This is why we see a rally in price in the period after each halving (the left of the chart).” One remarkable aspect of the second halving is just how unremarkable the Bitcoin price charts look today. The exchange rate is now hovering around the $645 or ¥4330 level, about 2.5% below its level the previous day. For a currency that just recently saw swings of $100 a day, and especially in a time of great volatility around the effects of the Brexit vote, this is practically completely flat. Bitcoin halving occurs approximately once every 4 years. This event is at the core of the hypothesis of the cyclical nature of the cryptocurrency market. Halving causes a supply shock, so many believe it is a catalyst for long-term increases in the BTC price.

  3. But video games are still a nascent market, Mr. Petrozzo said. Interest in buying old games has picked up some in recent years, but many vintage games have been opened and played, causing them to lose value, he said, and investors are often intimidated from entering an industry they’re unfamiliar with. Look, Mario isn’t really going to die. But some Mario games will no longer be sold or playable after March 31, and Nintendo hasn’t explicitly said that Mario’s not going to die, so people are a little weirded out. The game shared a lot of similarities to other Square RPG’s though Mario himself looked more like the Mario from Super Mario 64 than any SNES game with Mario in it. It was the first ever Mario role playing game and the graphics, game play and humour ensured it got great reviews.

    Of course, in Kenshi, war will come to your doorstep whether you want it or not. This adds an extra layer of challenge that makes the base building even more exciting. Location is something else to consider. For example, the Holy Nation will keep you safe, but they’re misogynistic and racist. Is it worth it to build a base in their territory? Kenshi earns its spot on this list thanks to its uniqueness; this game has no right to be such a good city builder. Flotsam takes players away from a terrestrial setting and puts players in a flooded world. This extremely unique environment makes the game even more special when coupled with its special and one-of-a-kind mechanics. What starts out as a survival game, turns into an aquatic city builder, which finally turns into a game with a powerful, yet subtle, environmental lesson.
