Problem 66: Check Palindrome

Test Case Number

word

return

"racecar"

true

"hello"

false

"level"

true

Problem

Given a string word, write a solution function that returns true if the string is a palindrome, otherwise returns false.
Palindrome refers to a string that reads the same backward as forward.

Constraints

The length of word is between 1 and 100, inclusive.
word consists only of lowercase English letters.

Test Cases

Test Case Number	word	return
1	"racecar"	true
2	"hello"	false
3	"level"	true

Explanation for Test Case 1

For word = "racecar", the reversed string is identical to the original, so the return value is true.

Explanation for Test Case 2

For word = "hello", the reversed string is "olleh", which is different from the original, so the return value is false.

Explanation for Test Case 3

For word = "level", the reversed string is identical to the original, so the return value is true.
