Given a string s consists of upper/lower-case alphabets and empty space characters ’‘, return the length of last word in the string. If the last word does not exist, return 0. Note: A word is defined as a character sequence consists of non-space characters only. For example, Given s...
If an encoding process does not make the string shorter, thendonot encode it. If there are several solutions,returnany of them is fine. Example1: Input:"aaa"Output:"aaa"Explanation: There is no way to encode it such that it is shorter than the input string, so wedonot encode it. Exa...
Can you solve this real interview question? Length of Last Word - Given a string s consisting of words and spaces, return the length of the last word in the string. A word is a maximal substring consisting of non-space characters only. Example 1:
