(A) and (B) plz

\%These are given variables/values that will be used in the problems str1 = 'matlab is amazing!' str 2= 'ma' str 3= 'pe' num =68 name = 'Mirabel' age =15 \%For each of these problems, although you can see the values in the variables and could technically hardcode the answers, \%you are encouraged to figure out which of the functions covered can help you accomplish the task. \% Given the string in "str1", produce of vector of all of the starting indices of the substring in str2 (A) A=[11] \%Given the substring in 'str2', replaces all of the occurences of 'str2' in 'str1' with the new substring in 'str3' (B) B=[ 'pelab is amazing!']
