 * 
 *         Problem F: Marked Ancestor You are given a tree T that consists of N
 *         nodes. Each node is numbered from 1 to N, and node 1 is always the
 *         root node of T. Consider the following two operations on T:
 * 
 *         M v: (Mark) Mark node v. Q v: (Query) Print the index of the nearest
 *         marked ancestor of node v which is nearest to it. Initially, only the
 *         root node is marked. Your job is to write a program that performs a
 *         sequence of these operations on a given tree and calculates the value
 *         that each Q operation will print. To avoid too large output file,
 *         your program is requested to print the sum of the outputs of all
 *         query operations. Note that the judges confirmed that it is possible
 *         to calculate every output of query operations in a given sequence.
 * 
 *         Input The input consists of multiple datasets. Each dataset has the
 *         following format:
 * 
 *         The first line of the input contains two integers N and Q, which
 *         denotes the number of nodes in the tree T and the number of
 *         operations, respectively. These numbers meet the following
 *         conditions: 1 ??? N ??? 100000 and 1 ??? Q ??? 100000.
 * 
 *         The following N - 1 lines describe the configuration of the tree T.
 *         Each line contains a single integer pi (i = 2, ... , N), which
 *         represents the index of the parent of i-th node.
 * 
 *         The next Q lines contain operations in order. Each operation is
 *         formatted as "M v" or "Q v", where v is the index of a node.
 * 
 *         The last dataset is followed by a line containing two zeros. This
 *         line is not a part of any dataset and should not be processed.
 * 
 *         Output For each dataset, print the sum of the outputs of all query
 *         operations in one line.
 * 
 *         Sample Input 6 3 1 1 2 3 3 Q 5 M 3 Q 5 0 0 Output for the Sample
 *         Input 4
