translation: refine the translation of data_structure/summary

[nedchu]

If this pull request (PR) pertains to Chinese-to-English translation, please confirm that you have read the contribution guidelines and complete the checklist below:

• [x] This PR represents the translation of a single, complete document, or contains only bug fixes.
• [x] The translation accurately conveys the original meaning and intent of the Chinese version. If deviations exist, I have provided explanatory comments to clarify the reasons.

The last question in the Chinese version is not found in the initial machine translation. I have added the whole translation on this question.

In Line 10, I use (i)-(iii) to list the benefits of the complement code, because the sentence is too long.

In Line 59, I use the inverse operation of "first negate and then add 1" (the sentence between "" is newly added), to complete the meaning of the sentence.

Hi @nedchu, the line numbers between the old and new versions should match for review. Please check the formatting at https://github.com/krahets/hello-algo/pull/1374/files.

Fixed. I remove the blank Line 21 to match line. We need to add back this blank line after the revision, as the Chinese version uses it to separate the paragraph.
