Python.

make a function called recu_tup. This function returns tuples. This tuple contains the name and number. You should write a function recursively, which no for loop allowed!

def recu_tup(ex_tup,name,num)

#If ex_tup don't have the same name, then you should add a new tuple (name, num) in the ex_tup

#If ex_tup has the same name, then you should change the num of the name. For example ("hello",2) change to ("hello",5) "

Example output

example = (("A",3),("B",4),("C",5),("D",6))

print(recu_tup(example,"E",5))

output = (("A",3),("B",4),("C",5),("D",6),("E",5))

print(recu_tup(example,"D",2))

example = (("A",3),("B",4),("C",5),("D",2))
