2.Write a program to print a string in reverse without using built in methods?

Question

Accepted Answer

This program reverses a given string without using any built-in methods.

Iterate through the string from the last character to the first character.
Append each character to a new string to reverse the order.
Return the reversed string as the output.

Accepted Answer

def reverse_string(input_string):
    # Initialize an empty string to hold the reversed string
    reversed_string = ""
    
    # Iterate through the input string in reverse order
    for i in range(len(input_string) - 1, -1, -1):
        reversed_string += input_string[i]
    
    return reversed_string

# Example usage
input_str = "Hello, World!"
print("Original String:", input_str)
print("Reversed String:", reverse_string(input_str))

Accepted Answer

# Write Python code to reverse a string
def reverse_string(string):
    ans = ""
    for letter in string:
        ans = letter + ans # Prepend each letter to reverse the string
    return ans

result = reverse_string("abc")
print(result)

Accepted Answer

We can reverse a string using string slice operation

Str[::-1]

Accepted Answer

s=input("enter a string")

rev=""

for i in range(len(s)):

rev=s[i]+rev

print(rev)

Accepted Answer

def reverse(s):

return s[::-1]

str = 'hello world'

print(reverse(str))

Accepted Answer

def reverse_string(n):

for i in n:

reverse = n[::-1]

return reverse

n= "string"

prrint(reverse_string(n))

Accepted Answer

>>> Original_string = "this is a string"

>>> string=""

>>> for j in range(len(Original_string)):

j=j+1

a = (Original_string[-j])

string = string + a

>>>print(string )

Output: gnirts a si siht

OR

>>> K= Original_string.split()

>>> k1 = []

>>> for j in range(len(k)):

j=j+1

a = (k[-j])

#print(a)

k1.append(a)

>>> Revers_string= ' '.join(map(str, k2))

>>> print(Revers_string)

Output: string a is this

Accepted Answer

first calculate the length of the input value and then start printing in reverse using negative index
