在递归函数Recursion中，存在一个错误的地方：
Recursion(root.Left, targetSum, 0)
应该改为：
Recursion(root.Left, targetSum, curSum)
修正后的代码如下所示：
/*** Definition for a binary tree node.* type TreeNode struct {* Val int* Left *TreeNode* Right *TreeNode* }*/var result intfunc Recursion(root *TreeNode, targetSum, curSum int) {if root == nil {return}curSum += root.Valif curSum == targetSum {result++}Recursion(root.Left, targetSum, curSum)Recursion(root.Left, targetSum, 0)Recursion(root.Right, targetSum, curSum)Recursion(root.Right, targetSum, 0)}func pathSum(root *TreeNode, targetSum int) int {result = 0Recursion(root, targetSum, 0)return result}
这样修正后，函数应该能够正确计算路径和等于目标值的路径数量。
