Given an array of size N = 7 , perform the following operation using separate chaining . Draw the abstract representation of the array on a piece of paper. Trace all the changes. Use Multiply-Add-Divide (MAD) for compression method . The MAD method maps an integer i as follows: [ ( 푎 푖 + 푏 ) 푚 표 푑 푝 ] 푚 표 푑 푁 p is a prime number a is a number within the range of [1, p-1] b is a number within the range of [0, p-1] For this problem, assume p = 107, a = 1, b = 2. The items don’t have any values associated with them, meaning they are just integers. You will have to rehash when the number of items, n is greater than the total capacity N, i.e. when n>N.

2. The function $M(t) = t^k e^{-t^2}$ is defined in the domain $0 \le t < \infty$. (a) For each value of $k$, find the global (absolute) maximum and minimum of $M(t)$ exactly. Verify your result with a labeled plot generated by a plotting utility. (i) $k = 3$; (ii) $k = 7$. (b) Briefly describe the effect of the value of $k$ on the graph of $M(t)$. In particular, how do the locations and values of the minimum and maximum depend on $k$ for $k > 0$?
