用句子中的星号替换单词的程序

对于给定的句子作为输入，检查带有星号’ * ‘的特定单词。

例子 ：

Input : word = “computer”
text = “GeeksforGeeks is a computer science portal for geeks. People who love computer and computer codes can contribute their valuables/ideas on computer codes/structures on here.”
Output : GeeksforGeeks is a ******** science portal for geeks. People who love ******** and ******** codes can contribute their valuables/ideas on ******** codes/structures on here.

想法是首先将给定的句子拆分为不同的单词。然后遍历单词列表。对于单词列表中的每个单词，请检查其是否与给定单词匹配。如果是，则将单词替换为列表中的星号。最后，合并列表中的单词并打印。
