Develop a method that given an integer n returns the largest prime number k



5 1. Develop a method that given an integer n returns the largest prime number k <=n. 2. you can approximate  by using the following series: p ) develop a method that given an integer i returns ith approximation of  3. develop a method arraystatistics that given an array of fractional numbers a returns an array of fractional numbers b where: · b[0] is the smallest element in a · b[1] is the largest element in a · b[2] is the average of the elements in a · b[3] is the standard deviation of the elements in a standard deviation of a set of numbers is calculated using the following formula: where m is the average of the array. 4. develop a method that given an array of integers returns an array of integers containing the elements of the input argument in reverse order. 5. write a method that given two 2d arrays a and b returns the sum of the two arrays c where: cij = aij + bij iff the two arrays are compatible (have the same number of rows and columns). 2.="" you="" can="" approximate="" ="" by="" using="" the="" following="" series:="" p="" )="" develop="" a="" method="" that="" given="" an="" integer="" i="" returns="" ith="" approximation="" of="" ="" 3.="" develop="" a="" method="" arraystatistics="" that="" given="" an="" array="" of="" fractional="" numbers="" a="" returns="" an="" array="" of="" fractional="" numbers="" b="" where:="" ·="" b[0]="" is="" the="" smallest="" element="" in="" a="" ·="" b[1]="" is="" the="" largest="" element="" in="" a="" ·="" b[2]="" is="" the="" average="" of="" the="" elements="" in="" a="" ·="" b[3]="" is="" the="" standard="" deviation="" of="" the="" elements="" in="" a="" standard="" deviation="" of="" a="" set="" of="" numbers="" is="" calculated="" using="" the="" following="" formula:="" where="" m="" is="" the="" average="" of="" the="" array.="" 4.="" develop="" a="" method="" that="" given="" an="" array="" of="" integers="" returns="" an="" array="" of="" integers="" containing="" the="" elements="" of="" the="" input="" argument="" in="" reverse="" order.="" 5.="" write="" a="" method="" that="" given="" two="" 2d="" arrays="" a="" and="" b="" returns="" the="" sum="" of="" the="" two="" arrays="" c="" where:="" cij="aij" +="" bij="" iff="" the="" two="" arrays="" are="" compatible="" (have="" the="" same="" number="" of="" rows="" and="">
