🔗 Timestamps:
00:00 Introduction
01:16 input case1:
Input consists of two lines.
First line of input is an integer n
Second line of input contains n whitespace separated integers
ex 1:
5
p ? k r t
output:
[ 'p' '?' 'k' 'r' 't' ]
ex 2:
4
b a l i
output:
[ 'b' 'a' 'l' 'i' ]
10:17 input case2:
Input is one single line of input consisting of whitespace separated characters
ex 1:
a b c 0 1 2 3
output:
[ 'a' 'b' 'c' '0' '1' '2' '3' ]
ex 2:
0 3 ? p t
output:
[ '0' '3' '?' 'p' 't' ]
