Improve accuracy

0 or O, 1 or l? Practice Visually Similar Characters

Practice checking paragraph by paragraph using fictitious numbers to reduce visual confusion of letters, numbers and different horizontal lines.

Don’t judge just by the appearance of the whole string

A0O1l looks like a short number, but every character may affect the result. Identify them one by one first, and then enter them as they are. Practice using fictitious numbers, don't copy real codes or account information into the question bank, and don't guess a similar-looking character when you're not sure.

font and zoom can assist recognition

Enlarge the target text and observe the difference between the number zero, the letter O, and the lower case l. Magnification is for viewing clearly and does not automatically convert characters into equivalent forms. Hyphens, dashes, and dashes may also appear similar in appearance and should be copied using the original characters.

Check retention order with group

Group long strings into three or four characters in your mind, and compare them paragraph by paragraph after input, but do not add spaces to the output that are not in the original text. The number should also be checked for leading zeros and the total length to avoid missing the first character and the rest of the number will still appear normal.

Today’s practice and inspection

compiled five short numbers by himself, deliberately mixed numbers and letters, and entered them again after a period of time. Check each location and record the type of confusion. If the main difficulty is that you can't see clearly, you can optimize the font size first; if you still press the wrong key after you can see clearly, do the corresponding key connection training.
