#Create the new list and initialize the list markers.
new_list = list()
a = 0
b = 0
# Merge the two lists together until one is empty.
while a < len( collection1 ) and b < len( collection2 ) :
if collection1[a] < collection2[b] :

a += 1
else :
new_list.append( collection2[b] )
b += 1
# If collection1 contains more items, append them to new_list.
while a < len( collection1 ) :
new_list.append( collection1[a] )
a += 1
# Or if collection2 contains more items, append them to new_list.
while b < len( collection2 ) :
new_list.append( collection2[b] )
b += 1
