The problem statement does not clearly specify that all digits must be used and that the expression cannot start with a minus sign.
Right now, this case causes confusion:
{
'+1+2+3-4+5+6+78+9',
'+1+2+34-5+67-8+9',
'+1+23-4+5+6+78-9',
'+1+23-4+56+7+8+9',
'+12+3+4+5-6-7+89',
'+12+3-4+5+67+8+9',
'+12-3-4+5-6+7+89',
'+123+4-5+67-89',
'+123+45-67+8-9',
'+123-4-5-6-7+8-9',
'+123-45-67+89',
'-1+2-3+4+5+6+78+9' // <- unclear if this should be allowed
}
expected 12 to equal 11
Suggested clarification
Please explicitly state that:
All digits must be used in the given order
The equation cannot begin with -
This avoids ambiguity and ensures consistent solutions.

js fork approved

If I'm not mistaken :

• Lua already has a fixed test for this and random tests can generate word without vowels.
• JS random tests can generate this kind of test but I added a sample and fixed test in this fork.

Specs of the python tests are slightly different from the original language: the random tests generate words without any vowel.

All languages should be aligned:

• either this should be added to the fixed tests and random tests in all language
• or python random tests should not generate such a kind of input

Approved.

Approved.

Lua translation with merge conflicts resolved (author is inactive), can be approved.

Muito bom!

Added after the translation rework was approved.

Done.

Lua translation !

I was wondering what was expected in the case of a word only composed of consonants. Should it just stay the same ? Or should it stay the same and have a ay appended (which seems to be what's currently expected) ? I think it's worth mentionning in the description.

approved, if you want to make some more changes, suggest a new fork
