Python - Reverse Slicing of given string

Reverse slicing in Python is a way to access string elements in reverse order using negative steps.

Using Slicing ([::-1])

Using slicing with [::-1] in Python, we can reverse a string or list. This technique works by specifying a step of -1, which starts at the end of the sequence and moves backward, effectively reversing the order of elements. It's a concise and efficient way to reverse strings or lists.

s1 = "hello"
s2= s1[::-1]
print(s2)

Reversed String: olleh

Explanation

• The slicing syntax [::-1] starts at the end of the string and moves backward with a step of -1.

Using a Loop

Using a loop to reverse a string involves iterating through each character in reverse order and building a new string.

s1 = "hello"
s2 = ""
for char in s1:
    s2 = char + s2
print("Reversed String:", s2)

Reversed String: olleh

Explanation

• Each character is added to the front of the result string, effectively reversing the order.
