[LeetCode] 271. Encode and Decode Strings
Description Design an algorithm to encode a list of strings to a string. The encoded string is then sent over the network and is decoded back to the original list of strings. Machine 1 (sender) has the function: string encode(vector<string> strs) { // … your code return encoded_string; } Machine 2 (receiver) has the function: vector<string> decode(string s)…
