I will give you an integer (N) and a string. Break the string up into as many substrings of N as you can without spaces. If there are leftover characters, include those as well.

Example: 

N = 5;

String = "This is an example string";

Return value:
Thisi
sanex
ample
strin
g

Return value as a string: 'Thisi'+'\n'+'sanex'+'\n'+'ample'+'\n'+'strin'+'\n'+'g'

Example: 

n = 5;

str = "This is an example string";

Return value:
Thisi
sanex
ample
strin
g

Return value as a string: "Thisi"+"\n"+"sanex"+"\n"+"ample"+"\n"+"strin"+"\n"+"g"

Example: 

n = 5;

st = "This is an example string";

Return value:
Thisi
sanex
ample
strin
g

Return value as a string: 'Thisi'+'\n'+'sanex'+'\n'+'ample'+'\n'+'strin'+'\n'+'g'

Example: 

n = 5;

st = "This is an example string";

return value:
Thisi
sanex
ample
strin
g

return value as a string: "Thisi"+"\n"+"sanex"+"\n"+"ample"+"\n"+"strin"+"\n"+"g"
