#code

# required function taking two strings
def blend(s1, s2):
    # creating a string to store the combined value
    combined = ''
    i = 0  # current index value
    # looping as long as i is a valid index in either s1 or s2 or both
    while i < len(s1) or i < len(s2):
        # if i is valid in s1, appending char at index i to combined
        if i < len(s1):
            combined += s1[i]
        # if i is valid in s2, appending char at index i to combined
        if i < len(s2):
            combined += s2[i]
        # advancing i
        i += 1
    # returning combined string
    return combined


# end of blend() method


# code for testing, ignore if not needed
print(blend("ape", "BANANA"))  # aBpAeNANA
print(blend("BOOT", "gold"))  # BgOoOlTd

#output

aBpAeNANA
BgOoOlTd
