A pyramid of size n is formed as follows: First, the base of the pyramid consists of n numbers, given as a list: [x_1, x 2, , x_n] The next layer contains n-1 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x 1 + x_2, x_2 + x_3, , x_(n-1) + x_n] The next layer contains n-2 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x_1 + 2x 2 + x_3, x_2 + 2x 3 +x 4, , x_(n-2) + 2x_(n-1) + x_n] This process is repeated until the top layer which has only 1 number. Create a function that takes in a list of numbers in the bottom layer and returns the only number at the top layer. For example, we can form a pyramid having a base of [2, e, 2, 1]:

5.04-1. Bellman Ford Algorithm (1, part 1). Consider the scenario shown below, where at t=1, node e receives distance vectors from neighboring nodes d, b, h and f. The (old) distance vector at e (the node at the center of the network) is also shown, before receiving the new distance vector from its neighbors. Indicate which of the components of new distance vector at e below have a value of 1 after e has received the distance vectors from its neighbors and updated its own distance vector.
