Important Info

When solving competitive programming problems, it's often necessary to handle large inputs efficiently. In python the built-in input() function can be slow for large inputs, so it's recommended to use sys.stdin.readline for faster input.

Here's how you can use it

1. Import the sys module:

   import sys

2. Read a single line of input:

   line = sys.stdin.readline().strip()

   • sys.stdin.readline() reads a line from standard input.
   • .strip() removes any trailing newline characters.

3. Read multiple lines of input:

   import sys
   
   input = sys.stdin.read
   data = input().split()

   • sys.stdin.read() reads all input at once.
   • .split() splits the input into a list of strings based on whitespace.

4. Example:

   import sys
   
   input = sys.stdin.readline
   n = int(input().strip())
   arr = list(map(int, input().strip().split()))
   
   print(n)
   print(arr)
