Hi,

a very basic question…

I’d like to output the sequence “a b d e”, by testing if the current

element is == “b” then skip the next element and continue the loop. The

obvious solution doesn’t look rubyish to me, how could I use the first

or second attempt to get the desired solution?

## Patrick

a=%w( a b c d e )

# incorrect, outputs “a b c d e”

0.upto(a.size - 1) do |i|

puts a[i]

if a[i]==“b”

# skip next element

# but i won’t get affected

i += 1

end

end

# incorrect, outputs “a b c d e”

for i in 0…a.size

puts a[i]

if a[i]==“b”

# skip next element

# but i won’t get affected

i += 1

end

end

# incorrect, outputs nothing… is there a next_next ?

a.each do |elt|

puts elt

if elt==“b”

# skip next element

# ??

end

end

# this one works, but is ugly

i=0

while i < a.size

puts a[i]

if a[i]==“b”

# skip next element

i += 1

end

i += 1

end
