PYTHON BASIC PROBLEMS SOLUTIONS(HACKERRANK) Day-12 LEARN CODING EASILY. HOW TO BE GOOD PROGRAMMER? смотреть онлайн

Hello, Young Coders our channel will give you Hackerrank solutions.It will be very useful for you Kindly make use of it..You will be know how the format strings work in python and What is use of these format specifiers.If you face this situation you can use format function to get the result.

These Hackerrank solutions will be very useful for you.
Thanks for watching.

PROBLEM SOLVED IN THIS LECTURE::

PROBLEM LINK: https://www.hackerrank.com/challenges/python- lists/problem?isFullScreen=true

Consider a list (list = []). You can perform the following commands:

1. insert i e: Insert integer e at position .i
2 print: Print the list.
3. remove e: Delete the first occurrence of integer e .
4. append e: Insert integer c at the end of the list.
5. sort: Sort the list.
6. pop: Pop the last element from the list.
7. reverse: Reverse the list.

Initialize your list and read in the value of n followed by n lines of commands where each command will be of the 7 types listed above. Iterate through each command in order and perform the corresponding operation on your list.

EXAMPLE:

N=4
append 1
append 2
insert 3 1
print

1. append 1: Append 1 to the list, arr[1]
2: append 2 : Append 2 to the list, arr[1,2]
3. insert 3 1 : Insert 3at index 1 arr=[1,3,2] .
4 print: Print the array
.
Output:
[1, 3, 2]

INPUT FORMAT:

The first line contains an integer, n, denoting the number of commands.
Each line i of the n subsequent lines contains one of the commands described above.

CONSTRAINTS:

The elements added to the list must be integers.
Output Format

For each command of type print, print the list on a new line.

SAMPLE INPUT 0:

12
insert 0 5
insert 1 10
insert 0 6
print
remove 6
append 9
append 1
sort
print
pop
reverse
print

SAMPLE OUTPUT: 0

[6, 5, 10]
[1, 5, 9, 10]
[9, 5, 1]

SOLUTION:

if __name__ == '__main__':
N = int(input())
m=list()
for i in range(N):
s=input().strip().split(" ")
if(s[0]=="insert"):
m.insert(int(s[1]),int(s[2]))
if(s[0]=="print"):
print(m)
if(s[0]=="remove"):
m.remove(int(s[1]))
if(s[0] == "append"):
m.append(int(s[1]))
if(s[0] == "sort"):
m.sort()
if(s[0] == "pop"):
m.pop()
if(s[0] == "reverse"):
m.reverse()
