    what is wrong in my code: 

    def freqQuery(queries):
    num = {}
    list1 = []
    for i in range(0,q):
        if(queries[i][0] == 1):
            if queries[i][1] in num:
                num[queries[i][1]] = num[queries[i][1]] + 1
            else:
                num[queries[i][1]] = 1
            
        elif(queries[i][0] == 2):
            if queries[i][1] in num:
                 num[queries[i][1]] = num[queries[i][1]] - 1
            else:
                None            
        else :
            
            if queries[i][1] in num.values():
                list1.append(1)
            else:
                list1.append(0)
       
    return list1
