Given an array of integers, replace all the occurrences of elemToReplace with substitutionElem.

Example

For inputArray = [1, 2, 1]elemToReplace = 1, and substitutionElem = 3, the output should be
arrayReplace(inputArray, elemToReplace, substitutionElem) = [3, 2, 3].

我的解答:

def arrayReplace(inputArray, elemToReplace, substitutionElem):
for i in range(len(inputArray)):
if inputArray[i] == elemToReplace:
inputArray[i] = substitutionElem
return inputArray
def arrayReplace(inputArray, elemToReplace, substitutionElem):
return [substitutionElem if x==elemToReplace else x for x in inputArray]
