Given the fоllоwing dаtа structure:  а_list = [ {'a':'*','b':'#','c':'?'}, {'a':'&','b':'@'}, {'a':'%','b':'$','c':'!','d':'+'} ] Assume that 2 strings called t1 and t2 are initialized tо be empty. What will the following code print? for data in a_list[2]:    t1 += a_list[2][data]for data in a_list[0]:    t2 += a_list[0][data]print(t1+t2) [ans]
