I have a requirement in which i have to find out the index of the last space before the 50th position in a string.
is there any way other than spliting the string.
e.g. if string is - 'aaaa aaaa aaa........ aaa aaa'(length is more than 50)
i want the last space before 50th char.because i want to split the string before last word withing 50 th character
