let us talk about Priory analysis and all steely airy testing these are the two terms that are used for algorithms and the program's pretty any analysis is done over the bottom so what pre-analysis means we will do the analysis of an important by studying it into greater detail knowing how it is working and we get some results that is rate of analysis there what is that we will find out the time and the space consumed by a network the result of analysis and testing is done on the program so we run and execute the program and check it so we will know the washed-rind is checking how much how many seconds milliseconds it is taking and also the amount of memory dis consuming in terms of bytes so this is pre analysis the tunnel algorithm and the post a testing is done on programs well Iranian asses double would a little work on we know well that has worked on some not return in a particular language so they are language independent also they are Hardware independent they are not meant for a particular hardware but there is a program related program that is Hardware specific as well as the language specific and as well as operating system specific environment specific also so they are dependent on the hardware as well as the programming language used and here the result of the Sun is how we get the time of the space we don't get wash time three minutes ten minutes five seconds or milliseconds to know we will get the time function and we get the space function
