In this LeetCode Python tutorial, we'll tackle the classic "Two Sum" problem, which is often encountered in coding interviews. The challenge is to find two numbers in an array that add up to a given target value. We'll walk you through the problem statement, explain the algorithm, and provide Python code solutions with detailed explanations.

Key Highlights:

Understanding the "Two Sum" problem statement
Brute-force and optimized approaches
Python code implementation for both solutions
Step-by-step explanations and code walkthrough
Handling edge cases and constraints
Time and space complexity analysis

code used#code
data=[1, 2, 3, 4, 5]
target=7


final_dict={}
output=[]
for i,value in enumerate(data):
p=target-value
if p not in final_dict:
final_dict[value]=i
else:
output.append((final_dict[p],i))




#output [(2,3),(1,4)]
output=[]
n=len(data)
for i in range(n):
for j in range(i+1,n):
if data[i]+data[j]==target:
output.append((i,j))
