Write a function buildstr that will receive a character and a positive integer n. it will create and return a cell array with strings of increasing lengths, from 1 to the integer n. it will build the strings with successive characters in the ascii encoding test run of your function > > buildstr('a',4) ans = 1×4 cell array {'a'} {'ab'} {'abc'} {'abcd'} > > buildstr('c',4) ans = 1×4 cell array {'c'} {'cd'} {'cde'} {'cdef'} ***you have to use your problem solving skills to solve this, given the following hints***: 1. creating a cell array of strings str_array = {'a', 'ab'} 2. ascii encoding 'b' can be obtained by doing char('a'+1) 3. contatenating strings together using strcatopens in new tab strcat('a','b') = 'ab' strcat('ab', 'c') = 'abc'
