text: # Problem You are given an array A of size N, and Q queries to deal with.For each query, you are given an integer X, and you're supposed to find out if X is present in the array A or not.Input: The first line contains two integers, N and Q, denoting the size of array A and number of queries.The second line contains N space separated integers, denoting the array of elements Ai.The next Q lines contain a single integer X per line.Output: For each query, print YES if the X is in the array, otherwise print NO.Constraints: 1 ≤ N, Q ≤ 10^5 1 ≤ Ai ≤ 10^9 1 ≤ X ≤ 10^9 SAMPLE INPUT 5 10 50 40 30 20 10 10 20 30 40 50 60 70 80 90 100 SAMPLE OUTPUT YES YES YES YES YES NO NO NO NO NO # Solution ''' # Read input from stdin and provide input before running code name = raw_input('What is your name?\n') print 'Hi, %s.' % name ''' line1 = raw_input() arr_inp=[] for j in line1.split(' '): arr_inp.append(int(j)) line2 = raw_input() elemnt_array = {} for i in line2.split(' '): elemnt_array[int(i)] = 1 #elemnt_array.sort() #print elemnt_array, "and quries are", arr_inp[1] for i in range (arr_inp[1]): if int(input()) in elemnt_array: print "YES" else: print "NO"
