Python Solution

# Approach 1: using built in replace 
def replaceSpaces(mystring):
    return mystring.replace(" ", '%20')

# Approach 2: using built in split and join - which is faster than replace 
# Fails to address if there is a space at the end of the string.
def replaceSpaces(mystring):
    return "%20".join(mystring.split())

# Approach 3: using append TC: SC: ?
def replaceSpaces(mystring):
    charlist = []
    for i in mystring:
        if i == ' ':
            i = '%20'
        charlist.append(i)
    return ''.join(charlist)
