Recursive Binary Tree Traversals

Inorder Traversal:

void inorder(struct node *root)
{
  if(root != NULL)
  {
    inorder(root->left);
    printf("%d\t", root->data);
    inorder(root->right);
  }
}

Preorder Traversal:

void preorder(struct node *root)
{
  if(root != NULL)
  {
    printf("%d\t", root->data);
    preorder(root->left);
    preorder(root->right);
  }
}

Postorder Traversal:

void postorder(struct node *root)
{
  if(root != NULL)
  {
    postorder(root->left);
    postorder(root->right);
    printf("%d\t", root->data);
  }
}

    temp =

Core Linguistic Concepts

Determiners and Modifiers

The **Zero Determiner** refers to indeterminacy, often seen in phrases like "human beings who are rational."

• **Verb vs. Adjective:** Verbs often use the continuous form (e.g., *be + -ing*). Adjectives allow gradation (e.g., *very entertaining*).
• **Adverb vs. Adjective:** Adverbs modify verbs; adjectives modify nouns.

English Verb Classification

Main Verb Types

Verbs are classified based on their complementation patterns:

• **Intransitive (H):** Requires only the head/subject (e.g., *She signed, I am eating*).
• **Copulative (H + PCS):** Links the head/subject to a Predicate Complement of the Subject (e.g., *Turned red, seems an interesting idea, in good condition*).
• **Transitive (H + DO):** Requires a Direct

Hedging with S&P 500 Index Futures

SIF hedging: NF = V_F(antiguo) = F_o x Z. NF (Number of contracts) = V_p (portfolio value) / (V_F x B_p) (Beta). With this hedge, risk is removed. If the index goes up, the profit in the portfolio will be offset by losses in SIFs contracts and vice versa.

Example: S&P 500 falls 5%:

• In the portfolio: R_p = B_p x (-5%) = -10% of a portfolio of $10M, resulting in $9M (Final Value).
• In the SIFS contracts: S_i = 980 (S&P 500 value given) x 0.95 (100% - 5%) = 931. F_i = 931 x (1 + 0.04 x 5/12 (next month timeframe)) = 946.52. V_F = NF x (F_i - F_o) x Z (250).
• Gain on futures: V_F(New) / Equity portfolio value.
• Outcome stock portfolio: 2 x (-5%) = -10%.
• Final Value portfolio: $10M - $1M + V_F(New).

Sickle Cell Anaemia and Malaria Resistance

Sickle cell anaemia is a genetic mutation in humans characterized by a disorder in the amino acid sequence of the haemoglobin molecule. This results in red blood cells taking on a sickle shape. Malaria is caused by a parasite that thrives in red blood cells; consequently, individuals with sickle-shaped cells possess immunity to malaria. This explains why the condition is more prevalent in tropical regions where malaria is common. However, individuals with sickle cell anaemia typically have a significantly shorter life expectancy.
