Change the function changeStr(lst1,s1,s2) where lst1 is a list of strings, and s1 and s2 are strings so it looks at each element in the list and checks if the last three letters in the element are the same as those in s1. If the last three characters are the same as s1, it will change the string to replace s1 with s2 and save the element with the changed string. If the element does not end with s1, the original value of the element is kept. This function returns a list with the updated changes. s1 will always be of length 3. The list elements will always be a minimum of length 3
