String program

1. Remove extra space

name = "Kill     them      with   your    success"
result = ""
i = 0
while i < len(name):
    if name[i] != " ":
        result = result + name[i]
    else:
        if name[i-1] != " ":
            result = result + name[i]
    i += 1

print(result)

Output

2. Front space remove

name = "     kill them with your success"
i = 0
result = ""

while i < len(name):
    if name[i] != " ":
        break   
    i += 1

while i < len(name):
    result += name[i]
    i += 1

print(result)

Output

3. Remove last space

name = "Kill them with your success        "
result = ""

i = len(name)-1

while i >= 0:

    if name[i] == " ":
        i -= 1
        continue

    else:
        j = 0

        while j <= i:
            result += name[j]
            j += 1

        break

print(result)

Output

4. Reverse a word

name = input("Enter word:")
result = ""

i = len(name)-1

while i >= 0:
    result = result + name[i]
    i -= 1

print(result)

Output
