Can anyone solve this in R programming?

Write your own function my.wilcox. test which can perform both exact and normal approximation test for two-sided alternative hypothesis. Your function will compute the p-value using normal approximation if n, and n2 > 12. Otherwise, it will compute the p-value using exact test. Your function will return the test statistics W1 and W2, p-value p.value and a message indicating the type of test used (normal or exact). You may assume there is no ties in the data.
