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.

Comparison Sorting
Quicksort usually has a running time of , but is there an algorithm that can sort even faster? In general, this is not possible. Most sorting algorithms are comparison sorts, i.e. they sort a list just by comparing the elements to one another. A comparison sort algorithm cannot beat  (worst-case) running time, since  represents the minimum number of comparisons needed to know where to place each element. For more details, you can see these notes (PDF).

Alternative Sorting
Another sorting method, the counting sort, does not require comparison. Instead, you create an integer array whose index range covers the entire range of values in your array to sort. Each time a value occurs in the original array, you increment the counter at that index. At the end, run through your counting array, printing the value of each non-zero valued index that number of times.


All of the values are in the range , so create an array of zeros, . The results of each iteration follow:

i	arr[i]	result
0	1	[0, 1, 0, 0]
1	1	[0, 2, 0, 0]
2	3	[0, 2, 0, 1]
3	2	[0, 2, 1, 1]
4	1	[0, 3, 1, 1]

The frequency array is . These values can be used to create the sorted array as well: .

For this exercise, always return a frequency array with 100 elements. The example above shows only the first 4 elements, the remainder being zeros.

Given a list of integers, count and return the number of times each value appears as an array of integers.

Function Description

Complete the countingSort function in the editor below.

countingSort has the following parameter(s):

  • arr[n]: an array of integers


  • int[100]: a frequency array

Input Format

The first line contains an integer , the number of items in .
Each of the next  lines contains an integer  where .


Sample Input

63 25 73 1 98 73 56 84 86 57 16 83 8 25 81 56 9 53 98 67 99 12 83 89 80 91 39 86 76 85 74 39 25 90 59 10 94 32 44 3 89 30 27 79 46 96 27 32 18 21 92 69 81 40 40 34 68 78 24 87 42 69 23 41 78 22 6 90 99 89 50 30 20 1 43 3 70 95 33 46 44 9 69 48 33 60 65 16 82 67 61 32 21 79 75 75 13 87 70 33  

Sample Output

0 2 0 2 0 0 1 0 1 2 1 0 1 1 0 0 2 0 1 0 1 2 1 1 1 3 0 2 0 0 2 0 3 3 1 0 0 0 0 2 2 1 1 1 2 0 2 0 1 0 1 0 0 1 0 0 2 1 0 1 1 1 0 1 0 1 0 2 1 3 2 0 0 2 1 2 1 0 2 2 1 2 1 2 1 1 2 2 0 3 2 1 1 0 1 1 1 0 2 2

  1. Real money online casinos are virtual casinos that allow players to wager and win real money. There are a variety of casino games available, but not all of them have the same RTP (return to player) percentage. Games with a higher RTP tend to be more favorable to the player, as they have a higher chance of winning. Some of the most popular high RTP casino games include slots, blackjack, and roulette. Big things are happening in online gambling in NY and we look at the most probable New York online casinos to likely go live first. It looks like it will be early in 2023 when New York follows New Jersey and legalizes online casino games and real money online casinos and slot games. The NY Senate has promised to prioritize the passing of a bill to allow casino sites to operate online. The biggest operators and best online betting sites likely will be the ones that go live first. Commercial land-based casinos in New York that already have partnerships in place with the big betting operators running sportsbooks etc. will look to enhance their turnover with an online casino offering.
    New players in Michigan can take advantage of the DraftKings Casino promo code for a $35 casino credit bonus to start playing. You can then choose your deposit match bonus either 100% match up to $2,000 with a 15x playthrough requirement OR 100% match up to $100 with a 1x playthrough requirement. Ignition: Make your first crypto deposit to redeem a 150% online casino bonus of up to $1,500. Then, fund your account once more to claim an identical 150% poker bonus. Total bonus value: Up to $3,000. NJ online casinos are live and legal with 33 apps available in the state. Virtually every game that you can think of can be found in New Jersey, including online slot machines, table games, and live dealer options. Legal Sports Report only promotes legal and regulated online casinos in New Jersey. You can find the best bonuses at NJ online casinos here as well as reviews of the top casino apps.

  2. Writing with style and getting good compliments on the article is quite hard, to be honest.But you’ve done it so calmly and with so cool feeling and you’ve nailed the job. This article is possessed with style and I am giving good compliment. Best!

  3. The betting odds calculator will work for all types of bets: point spread, moneyline, total, or props. For any bet that has a handicap value set (ex: a point spread of -6, total of 43, etc.), you can ignore that part and simply enter the odds associated with that bet. For example, with 5 1 (“five to one”) odds one stands to gain 5 dollars for each dollar staked, and the payout is for 10 dollars for each dollar staked. 12 5 (“twelve to five”) odds mean one wins 12 dollars for every 5 dollars staked, and a payout is 12 + 5 = 17 dollars for every five dollars staked. Our odds calculator outputs the odds in all four types, as well as the payout and winnings. Unfortunately, $6+ expected value opportunities don’t come along too often (only 38 times so far this year), because Vegas is pretty in-tune with what’s going on with these teams, and they also set the lines slightly in their favor no matter what (this is referred to as vig).
    Rodgers is a favorite to either land in Las Vegas or New York. Both those two teams have odds of +4500 or higher to win the Super Bowl this year. Aaron Rodgers and Davante Adams would be a movie. But then again, the Jets, with Rodgers at quarterback and that stellar defense, could shock the AFC. Aside from the Bills, the Eagles are the only team in the NFL that ranks top five in both offensive and defensive DVOA this season. Philadelphia has had the best record in the league all year and should earn the No. 1 seed in the NFC, but its Super Bowl price has recently dropped due to Jalen Hurts’ shoulder injury. If Hurts returns to full health by the postseason, the Eagles will be the clear favorites to win the NFC. When looking at the Super Bowl spread, the betting sheet will show each competing team, along with a positive or negative number alongside it. The negative number indicates the favored team and the minimum point difference they need to win by for your wager to pay out if you bet on them. The positive number shows the underdog and how many points or less they need to lose for a bet to pay.

    “É como a Copa do Mundo tem nos mostrado: jogo é jogo. Tantas zebras acontecem, pensamos que vai dar um resultado e ocorre outro. Jogue como diversão e apenas aposte o que não fará falta”, diz Habib. “O jogo se baseia em sorte e não depende de habilidade, lógica ou inteligência do jogador. Ou seja, é um jogo de azar”, explica Rosângela Llanos, perita da Secrim, empresa especializada em Perícias Criminais Forenses e Investigações Criminais. Você já ouviu falar no jogo do foguete que ganha dinheiro? Pois bem, explicamos… No game você aposta na decolagem de uma aeronave. É preciso finalizar o lance antes que a nave exploda.
