Sample input and output:
Input: (hi)

(
hi
)


Input: (hi hello)

(
hi
hello
)


Input: (hi hello (bye))

(
hi
hello
(
bye
)
)

Just did a quick one in Python:

str1 = "(hi hello (bye))"
#print (str1)

strx=""
for i in range(len(str1)):
    if (str1[i] == "(") or (str1[i] == " "):
        strx+=str1[i]+"\n"
    elif (str1[i]== ")"):
        strx+="\n"+str1[i]
    else:
        strx+=str1[i]

print (strx)

Output:

(
hi 
hello
)
