You are given a string moves of length n consisting only of characters 'L', 'R', and '_'. The string represents your movement on a number line starting from the origin 0.
In the ith move, you can choose one of the following directions:
moves[i] = 'L' or moves[i] = '_'moves[i] = 'R' or moves[i] = '_'Return the distance from the origin of the furthest point you can get to after n moves.
\n
Example 1:
\n\n\nInput: moves = "L_RL__R"\nOutput: 3\nExplanation: The furthest point we can reach from the origin 0 is point -3 through the following sequence of moves "LLRLLLR".\n\n\n
Example 2:
\n\n\nInput: moves = "_R__LL_"\nOutput: 5\nExplanation: The furthest point we can reach from the origin 0 is point -5 through the following sequence of moves "LRLLLLL".\n\n\n
Example 3:
\n\n\nInput: moves = "_______"\nOutput: 7\nExplanation: The furthest point we can reach from the origin 0 is point 7 through the following sequence of moves "RRRRRRR".\n\n\n
\n
Constraints:
\n\n1 <= moves.length == n <= 50moves consists only of characters 'L', 'R' and '_'.'_’ will be replaced with the same character.'_’ with the character that occurs the most. Compiled with clang 11 using the latest C++ 20 standard.
