如何检查一个字符串在GO中是否具有n个以上的重复模式？

I want to check if a string contains repetitive patterns above a threshold .

For example, these two strings both exceed a threshold of 2:

"xyzxyzxyz" // contains "xyz" 3 times in succession
"abxyxyxyns" //  contains "xy" 3 times in succession

Does anyone know how this is possible?

Use the "repetitions" modifier.

re := regexp.MustCompile(`(xy){3,}`)      // match "xy" 3 or more times
fmt.Println(re.MatchString("abxyxyns"))   // false
fmt.Println(re.MatchString("abxyxyxyns")) // true

The available options for the regpexp package's RE2 implementation are documented here:
