Answer:
{"double", "char", "char", "double"} will be stored in word.
Explanation:
Given the word is an array of four strings, {"algorithm", "boolean", "char", "double"}. Hence, the length of the word array is 4.
The for-loop will only run for two iterations due to i < word.length/2, with i = 0 (first loop) and i = 1 (second loop).
In the first loop,
- word[word.length - 1 - i] = word[4 - 1 - 0] = word[3] = "double"
- Hence, the string "double" will be assigned to word[0] and overwrite "algorithm"
In the second loop,
- word[word.length - 1 - i] = word[4 - 1 - 1] = word[2] = "char"
- Hence, the string "char" will be assigned to word[1] and overwrite "boolean"
At last, the word array will hold {"double", "char", "char", "double"}
