Write a python algorithm as a function which takes string s as input and which returns an other string obtained from s by removing all the spaces charachters at the beginning of the string s and the spaces at the end of the string s without using the lstrip() neither any predefined method. Exemple if
s = " Hello "
, the function returns the string:
s = "Hello"
def removeSpace(s): n = len(s) # initializing the number of existing space at the end of s j = 0 while(s[n-1-j]) == " ": j = j + 1 s = s[:n-j] # initializing the number of existing space at the begining of s i = 0 while s[i] == " ": i = i + 1 s = s[i:] return s # Testing algorithm s = " Hello World " print("s with spaces : " ,"'"+ s +"'") # display : s with spaces : ' Hello World ' print("s without spaces:" ,"'"+ removeSpace(s)+"'") # display : s without spaces: 'Hello World'
