This module is for TwoSum operations and subsequence checks

TwoSum Library

A simple Python library to find indices of numbers that sum up to a target in sorted arrays and check for subsequences.

Functions

1. twoSumK(numbers: List[int], target: int) -> List[int]

Description:
This function takes a sorted list of integers and a target integer. It returns the 1-based indices of the two numbers that add up to the target.

Parameters:

• numbers (List[int]): A sorted list of integers.
• target (int): The target sum.

Returns:

• List[int]: A list containing the 1-based indices of the two numbers that sum to the target. Returns an empty list if no such numbers exist.

Example:

result = twoSumK([2, 7, 11, 15], 9)  # Output: [1, 2]

2. twoSum(numbers: List[int], target: int) -> List[int]

Description:
This function operates similarly to twoSumK, but it returns 0-based indices.

Parameters:

• numbers (List[int]): A sorted list of integers.
• target (int): The target sum.

Returns:

• List[int]: A list containing the 0-based indices of the two numbers that sum to the target. Returns an empty list if no such numbers exist.

Example:

result = twoSum([2, 7, 11, 15], 9)  # Output: [0, 1]

3. is_subsequence(s: str, t: str) -> bool

Description:
This function checks if string s is a subsequence of string t.

Parameters:

• s (str): The string to check as a subsequence.
• t (str): The string in which to check for the subsequence.

Returns:

• bool: Returns True if s is a subsequence of t, otherwise False.

Example:

result = is_subsequence("abc", "ahbgdc")  # Output: True

Installation

To use this library, you can clone the repository or install it via pip (if published):

pip install your_library_name

Usage

Import the functions into your script as follows:

from your_library_name import twoSumK, twoSum, is_subsequence

# Example usage
indices = twoSumK([2, 3, 4], 6)
print(indices)  # Output: [1, 3]
