Arithmetic Mean

The following C++ code calculates the arithmetic mean of numbers from 1 to n:

int main() {
    int n;
    double suma = 0;
    cout << "Vnesi broj: ";
    cin >> n;
    if (n <= 0) {
        cout << "Brojot na elementi mora da bide pogolem od 0!" << endl;
        return 1;  
    }
    for (int i = 1; i <= n; i++) {
        suma += i;  
    }
    double sredina = suma / n;
    cout << "Aritmetichkata sredina na broevite od 1 do " << n << " e: " << sredina << endl;
    return 0;
}

Sum

The following C++ code calculates the sum of numbers from 1 to n:

int main() {
    int n, sum = 0;
    cout << "Vnesi broj n: ";
    cin >> n;
    for (int i = 1; i <= n; i++)

Letter to a Friend About a Trip

From: [Your Name]

To: [Friend’s Name]

Subject: My Trip to Canada

Hi [Friend’s Name],

How are you? I have amazing news! I’m going to Canada for three weeks to study English!

I’ll be arriving on January 15th and staying at a student residence close to the school. My course has 20 lessons a week, and I’ll take morning classes. In the afternoons, I plan to join some activities, like city tours and maybe trying fun things like ice skating. I also want to explore and enjoy Canadian food. It’s going to be so exciting!

I hope you’re doing well. Do you think I should pack anything special for the trip? Let me know!

Take care,

[Your Name]

Essential Algorithms and Data Structures

Longest Increasing Subsequence (LIS):

• Subproblem: dp[i] = length of LIS ending at index i
• Recursion: dp[i] = max(dp[j] + 1 for j < i and arr[j] < arr[i])
• Base case: dp[i] = 1 (every element is a subsequence of length 1)
• Time Complexity: O(n^2), O(n log n) with binary search optimization.

Longest Alternating Subsequence (LAS):

• Subproblem: dp[i][0] (increasing), dp[i][1] (decreasing)
• Recursion: dp[i][0] = max(dp[j][1] + 1 for j < i and arr[j] < arr[i]), dp[i][1] = max(dp[j][0] + 1 for j < i and arr[j] > arr[i])
• Base case: dp[0][0] = 1, dp[0][1] = 1
• Time Complexity: O(n^2)

0/1 Knapsack Problem:

• Subproblem: dp[i][w] = maximum value for the first i items and weight limit w
• Recursion: dp[i][w] = max(

Scott Galloway on the Modern Business Landscape

Professor Scott Galloway highlights oil as the most important commodity. However, in the current era, he argues that social media platforms like TikTok are the real deal, although he believes TikTok should be banned due to its links with the CCP, which he considers a tool of espionage.

Innovation Strategies of Supermajors

Supermajors, or large oil and gas companies, are employing innovative strategies such as:

• Emotional Resonance: Engaging users through comments and attractive content.
• Offloading

We must remember that when the division happened, most of the Muslims did not follow Ali; they followed Abu Bakr. During Ali's imamate in 656, the third Caliph Rashidun, the first Fitna war (656-661) occurred. It ended because Ali agreed to negotiate with his enemy to avoid the brutal civil war. However, this was seen as treason by some Shia extremists because they argued that power given by God could not be negotiated. Therefore, Ali was assassinated.

The Rise of Muawiya and Imam Hasan's Role

After the end of the first Fitna, Muawiya ruled as caliph from 661 to 680. Hasan, the second Imam (661-670), accepted Muawiya as caliph because he did not want to continue the war that opposed Sunni vs. Shia. However, Shia thought Hasan practiced Taqiyya...

Prehistory: The Dawn of Humanity

Prehistory is a term used to refer to the first and longest phase or age into which human history has been divided by Eurocentric/Western academic tradition. It covers most of the human past, around 2.8 million years, since the appearance of the first member of the hominid family: *Homo habilis*, the first to make and devise tools made of stone. At the beginning of the 19th century, a Danish archaeologist, Christian Jürgensen Thomsen, concluded that objects and tools made of stone tended to be older than those made of metal. He divided this remote human past into two main phases: the Stone Age and the Metal Age.

Subdivisions of the Stone Age

A few decades later, another archaeologist, John Lubbock, after studying... Continue reading "Human Prehistory: From Stone Tools to the Holocene" »
