<Codesignal> checkPalindrome

Easy

Given the string, check if it is a palindrome.

Example

• For inputString = "aabaa", the output should be
  checkPalindrome(inputString) = true;
• For inputString = "abac", the output should be
  checkPalindrome(inputString) = false;
• For inputString = "a", the output should be
  checkPalindrome(inputString) = true.

Input/Output

• [execution time limit] 0.5 seconds (c)

• [input] string inputString

  A non-empty string consisting of lowercase characters.

  Guaranteed constraints:
  1 ≤ inputString.length ≤ 10^5.

• [output] boolean

  • true if inputString is a palindrome, false otherwise.

[C] Syntax Tips

// Prints help message to the console
// Returns a string
char * helloWorld(char * name) {
    char * answer = malloc(strlen(name) + 8);
    printf("This prints to the console when you Run Tests");
    strcpy(answer, "Hello, ");
    strcat(answer, name);
    return answer;
}

Solution

bool checkPalindrome(char *inputString)
{
	for(int i=0;i<strlen(inputString)/2;i++)
		if(inputString[i]!=inputString[strlen(inputString)-i-1])
			return false;
	return true;
}
