In the first line of standard input, there are two integers, N and Q （1<=N,Q<=1 000 000）, separated by a single space, that specify the number of instructions in Byteasar's program and the number of running time queries (for different numbers of processing units).
In the second line of input, there is a sequence of Q integers, K1,k2,…Kq (1<=Ki<=1 000 000), separated by single spaces: Ki is the number of processing units in Byteasar's i-th query.
In the third and last input line, there is a sequence of N-1 integers, A2,A2…An (1<=Ai<i), separated by single spaces: Ai specifies the number of the parent instruction of the instruction number i. The instructions are numbered with successive integers from 1 to N, where the instruction no. 1 is the first instruction of the program.
