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.

Counting Valleys – Hacker Rank Solution

Problem:

An avid hiker keeps meticulous records of their hikes. During the last hike that took exactly  steps, for every step it was noted if it was an uphill, , or a downhill,  step. Hikes always start and end at sea level, and each step up or down represents a  unit change in altitude. We define the following terms:

  • A mountain is a sequence of consecutive steps above sea level, starting with a step up from sea level and ending with a step down to sea level.
  • A valley is a sequence of consecutive steps below sea level, starting with a step down from sea level and ending with a step up to sea level.

Given the sequence of up and down steps during a hike, find and print the number of valleys walked through.

Example

The hiker first enters a valley  units deep. Then they climb out and up onto a mountain  units high. Finally, the hiker returns to sea level and ends the hike.

Function Description

Complete the countingValleys function in the editor below.

countingValleys has the following parameter(s):

  • int steps: the number of steps on the hike
  • string path: a string describing the path

Returns

  • int: the number of valleys traversed

Input Format

The first line contains an integer , the number of steps in the hike.
The second line contains a single string , of  characters that describe the path.

Constraints

Sample Input

8

Sample Output

1

Explanation

If we represent _ as sea level, a step up as /, and a step down as \, the hike can be drawn as:

_/\      _
   \    /
    \/\/

The hiker enters and leaves one valley.

Its competitor, the Epic Games Store, has its fair share of exclusive premiere titles that Steam Deck enjoyers naturally wouldn’t be able to play. Epic Games Store, on the other hand, is tailored to the more popular titles on the scene. You’ll find substantially fewer offerings of unique titles and ones that go under the radar. The only angle they have over Steam is Epic Games titles, such as Fortnite and Rumbleverse which are exclusive to the store. Epic Games Store also shovels out two free games a week, however, when put up to Steam’s vast library of free games, it’s hard to even compare.

You can move the top card and place the top cards on the other cards as long as there is a sequence. For example, you can move a top card #4 and place it on another top card #5. Complete the sequence until you get a complete suit from king to ace. Play Spider Solitaire Classic online on your PC.

First, many online casinos offer a no deposit bonus, which means you can sign-up as a new player and try out casino games, including slots, without depositing any money.\nSecond some sites offer you the chance to play casino slot games in demo mode, which means you can get limited spins on a real money game before you need to deposit and play with real money. Demo versions of new slots are always provided in slot machines from the Aristocrat provider. However, apart from this software provider, many others offer free slots to their players. The most famous representatives include the following companies: Microgaming, Aristocrat, NetEnt, Pragmatic Play, RTG, IGT, Konami. Many reliable gambling platforms provide players with various bonuses and promotions. Very often, players are provided with free spins, with which you can try and evaluate the game without investing money. The bonus policy of each casino is unique, so you can get free spins in different amounts and for different slots.

    Players should always check what kind of slot game they are playing. That’s not to say Vegas slots will never offer payouts as big as a progressive jackpot slots. However players expecting to win millions on a penny slot machine will be left disappointed. Finally, players should always check the payout percentage of a game. Find a slot title with an RTP of 90% or higher; these games will usually pay out more often than slot machines with an RTP below this.
