Military Time in Ruby

Question

My code:
a=gets
b=a[0..4]
ans=""
if a[-2]=="P"
if b[1]==":"
ans=(b[0])+12+b[1...]
else if b[0...2]== "12"
ans="12"+b[2...]
else
ans=((b[0..2]).to_i+12).to_s+b[2...]
end
end
else
if b[1]==":"
ans="0"+b[0...]
else if b[0..2]=="12"
ans="00"+b[2...]
else
ans=b
end
end
end
print(ans)

Keep getting the #4 case wrong.
Does anybody have any ideas?

Answer 4

input = gets.chomp

if input.include?("AM")
if input[1] == ":"
time = "0" + input[0] + ":" + input[2..3]
else
time = input[0..1] + ":"+ input[3..4]
end
else
if input[1] == ":"
time = (input[0].to_i + 12).to_s + ":" + input[2..3]
else
time = (input[0..1].to_i + 12).to_s + ":"+ input[3..4]
end
end

puts time
