Below is a MAPLE procedure called find2s, which writes a given prime as a sum of two squares if such a sum exists, otherwise it prints the statement, "p is not the sum of two squares." The procedure checks whether the input is a prime. Fill in the missing parts. Below you will find some sample output with which to check the procedure. find2s-proc(p:: local find :- 0; .. for a from 1 to trunc(sqrt (p/2)) do if issqr (c) then find := 1: end if; end do; if find-0 then end if; end proc: Below is a MAPLE procedure called find2s, which writes a given prime as a sum of two squares if such a sum exists, otherwise it prints the statement, "p is not the sum of two squares."
