out of 4 testcases 2 went wrong can u plz correct where i done mistake
@A17CRX0016,
Take as input N, a number. Take N more inputs and store that in an array. Write a recursive function which tests if the array is a palindrome and returns a Boolean value.
Now you are taking input as strings which stores only the first number. Hence you will always get answer as true.
Also, try implementing a recursive solution instead of a iterative solution as mentioned in the question.
And print “false” instead of “no”.
Input:
5
3
2
1
2
4
Your answer:
true
Correct answer:
false
