In this exercise, a string is passed to a method and a new string has to be returned with the first character of each word in the string.
For example:
```
"This Is A Test" ==> "TIAT"
```
def make_string(k):
    k=k.split()
    j = ""
    for i in range(len(k)):
        j += k[i][0]
    return j

def make_string(k):
    k=k.split()
    j = ""
    for i in range(len(k)):
        j += k[i][0]
    return j
