Dont know how to take string input

#1

in the videos above, sorting of integers is only explained. please tell about the steps or method of solving this problem

@jatin111,

Take string input using .next() like for int we use .nextInt()

you need to write a sort function for that. If the string lengths are same compare then char by char.

Don’t forget: if a string is present completely as a prefix in another string, then string with longer length should come first. Eg bat, batman are 2 strings and the string bat is present as a prefix in Batman - then sorted order should have - Batman, bat.

how to check the last condition that you mentioned

#4

@jatin111,

        while (i < s1.length() && i < s2.length()) {

            if (s1[i] > s2[i]) {

                return 1;
            } else if (s1[i] < s2[i]) {
                return -1;
            }
            i++;

        }

        if (s1.length() > s2.length()) {
            return -1;
        } else {
            return 1;
        }

This is a pseudo code of how your comparator should look like. Now the final condition is taken care of automatically. If length of s1> length of s2 then return -1. Swap the strings only when returned value is greater than 0.
