'''1.
   If you are a list of integers (that are non negative) write a program to return an integer list of the  
   rightmost digits. 
   right([1,22,94])   ->[1,2,4]
   right([10,0])      ->[0,0]
'''

def right(lst):
    new_lst = []

    for item in lst:
        lst = [int(a) for a in str(item)]
        new_lst.append(lst[(len(lst))-1])

    return new_lst

print(right([1,22,94]))
print(right([10,0]))


'''2.
If you have a list of strings, write a program to return a list where a * is added at the end of each string.
addstar["a","hello","hai","*"]) --->["a*","hello*","hai*","**"]
'''

def addstar(lst):
    return [i+'*' for i in lst]

print(addstar(["a","hello","hai","*"]))

'''3.
If you have a list of strings, write a program to display a list where each input string is converted to   
lower case.
lower(["Choc"]) --------> choc
'''

def lower(lst):
    return [i.lower() for i in lst]

print(lower(["Choc"]))



'''
4.Consider a list of strings, return a list where each string is replaced by 3 copies of the concatenated string example:
Input ->(["a","bb"]) ------> Output ->(["aaa","bbbbbb"])
'''

def copy(lst):
    return [i+i+i for i in lst]


print(copy(["a","bb"]))
