**Algorithm Analysis: Counting Multiplications****Problem Statement:**Determine the exact number of multiplications performed in the following segment of an algorithm. Assume \( a_1, a_2, \ldots, a_n \) are positive real numbers, with \( n = 11 \).**Algorithm Segment:**```for i = 1 to n m_i = a_i; for j = i + 1 to n m_i = m_i a_j;```**Explanation:**1. **Outer Loop:** The variable \( i \) iterates from 1 to \( n \).2. **Initialization:** For each \( i \), the variable \( m_i \) is initialized as \( a_i \).3. **Inner Loop:** The variable \( j \) iterates from \( i + 1 \) to \( n \). - In each iteration of the inner loop, \( m_i \) is updated as \( m_i \times a_j \).**Total Multiplications:**To find the total number of multiplications:- For each iteration of \( i \), the inner loop runs \( (n - i) \) times (since \( j \) starts at \( i + 1 \)).- Therefore, the number of multiplications for each \( i \) is \( n - i \).Summing the multiplications over all iterations of the outer loop:\[\sum_{i=1}^{n} (n - i) = (n - 1) + (n - 2) + \ldots + 1 + 0\]This is the sum of the first \((n-1)\) natural numbers, which can be calculated using the formula:\[\frac{(n-1) \times n}{2}\]Substitute \( n = 11 \):\[\frac{10 \times 11}{2} = 55\]Thus, the exact number of multiplications performed is 55.

Scientists have developed a recursion formula to determine the number of insects in a given population for each interval, n, of time, . an = kan-1(1-an-1), where k is a constant called the Malthusian factor. a. Assuming n is measured in weeks, calculate the insect population for weeks 2, 3, and 4 if the initial population is 112, and the Malthusian factor for this population is -9.5.

How many numbers have digits which are all ”1”s and ”2”s, and thedigits add up to 8? A few such numbers are 12212, 112121, and 112121. (HINT: breakthe list into cases and count each one. You can count them by hand, but you will savea lot of time if you apply the right formula.)
