This is a pretty easy problem. I think you should learn something about combinatorics to solve this kind of problemâ€Ļ
You can read “āĻ•āĻŽā§āĻŦāĻŋāĻ¨ā§‡āĻŸāĻ°āĻŋāĻ•ā§āĻ¸ā§‡āĻ° āĻšāĻžāĻ¤ā§‡āĻ–ā§œāĻŋ” to develop your basic combonatorial knowledgeâ€Ļ

In the word GONITZOGGO, there are 10 letters and G,O have came 3 times. So we can arrange it in 10!/(3!3!) ways
