Answer 1

Abc def In this method you search first the bigest number and you put it in the last of the array, and whene you do that for the first time;: you didn't need to compare the last element in the array by someone cuz you know that is the bigest one:; and that why you use (j<max-i)..,,

Answer 2

okey i get it but why is j=1

Answer 3

Abc def j start by 1 cuz in if statment we compare with str[j-1] and str[j] :: if u want u can let j start by 0 but inside if statment u should compare between str[j] and str[j+1] :;;
