Write two functions to compute and return the following summation sigma_a^b i. First function computes the summations and inserts it into an array and second function returns the values using the array. Prototype of the first function is given below. void precomputesummation(int data[], int n) data is an array that will store computed values and n is the size of the array. Data[k] will have the following value stored in it sigma_1^k i. Compute all the values of data[k] inside this function. Note that you can compute all the values of the array using a single loop. Prototype of the second function is given below, data is an integer array of precomputed values, n is the size of the array, a and b are the starting and ending indexes for the summation. void findsummation(int data[], int n, int a, int b) data is an integer array of precomputed values, n is the size of the array, a and b are the starting and ending indexes for the summation. This function can be implemented without using a loop using values of the data array. Consider the following equation as a hint. sigma_1^b i = sigma_1^a - 1 i + sigma_a^b
