# Find Symmetric Poems

![](https://github.com/LingDong-/magic-square-poems/raw/main/illustration.svg)

I got inspirations from https://github.com/LingDong-/magic-square-poems .

"Observe the above 5x5 matrix of Chinese characters: when read horizontally, it consists of five lines from five different poems, and so does it when read vertically, of the exact same lines. "

I prefer symmetric matrix but not magic matrix, because I think it's a symmetric matrix.

Observe that when a matrix is symmetric, as in these cases, the matrix is equal to its transpose.

To solve this problem, I implemented a quicker parallel alogorithm. It only takes 36 seconds to find the symmetric poems.

*Run*

```

go run main.go

```

*Output*

```

❯ go run main.go

夜深来客稀

心如七十人

七十未成事

十年成底事

人间事事慵
