{python language}Dan’s recently announced that he’s teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order.In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s.Notethatifastudentis interested in taking multiple courses, they need to send multiple emails, one per course.Upon receivinga message c s,Danl ooks at the list of students already enrolled in course c. If there’s already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course.Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that “a” and “A” are considered the same letter). For example, “Josh” and “Josh” are too similar. “Sam” and “CaM” are too similar as well. However, neither “Max” and “Cat” nor “Ann” and “Anne” are too similar.Dan has a lot of students and teaches a lot of courses. Consequently, it would take him forever to process the messages sent by the students one-by-one manually. Instead, he’s asking you to help him out by writing a program that takes in the messages as the input and outputs, for every course, the list of the students enrolled in that course in the order of their enrolments.
Input
The first line of the input consists of two space-separated integers n and m, denoting the number of secret courses Dan is teaching next semester and the number of messages sent by the students, respectively.
The m messages will be described in the following m lines in chronological order. The i-th line describes the i-th message and consists of an integer c_i followed by a string s_i. This indicates that a student named s_i wants to enrol in course c_i.
Output
You should output exactly n lines. The i-th line should contain the names of the students enrolled in the i-th course in the order of enrolment (note that the line would be empty if there were no students enrolled in the course). These names should be separated by single spaces.
