Super confused, please answer and explain

IHomework 1 CIS 350: Data Structures and Algorithm Analysis Winter 2019 3. [10 pts.] Your statistician friend wants to implement an algorithm for computing the stan dard deviation i-0 of a dataset of n real-valued numbers ao, a1,... , an-1. Your friend, having found the following two algorithms, StandardDeviationl and StandardDeviation2, that perform the task correctly but not knowing which one to implement, is asking for your recommendation. Both algorithms take as input an n-element array A such that each element Aia for all 0,1,..,n-1 and output a real-value v with the corresponding standard-deviation evaluation. Assume that the sqrt function takes constant time and space. Please write your answers on the nert page. Algorithm 1 StandardDeviationl(A) 1: v-0 2: for i 0 to n-1 do 4: for j
