Package Testimport ("FMT")//number of lines const LINES int = 8//Yang hui triangle func showyanghuitriangle () {nums: = []int{}for I: = 0; i < LINES ; i++ {//Fill blank for J: = 0; J < (Lines-i); J + + {FMT. Print ("  ")}for J: = 0; J < (i + 1);  J + + {//current array length var = len (nums)//This position should generate the number var value int//each row the first element and the last element is 1, the middle element equals two elements above it and if j = = 0 | | j = = I {value = 1} else {value = Nums[length-i] + nums[length-i-1]}nums = append (nums, value) fmt. Print (Value, "")}//a newline fmt. Println ("")}}
