The array can contain up to 3000 integers within the range of -105 to 105.The problem requires finding all unique triplets in an array that add up to zero.

The task can be accomplished using a two-pointer approach. Firstly, the array is sorted, and then two pointers are initialized, one at the beginning and one at the end of the array. The third pointer starts from the beginning and moves towards the end, checking if the sum of the values at the three pointers is equal to zero.

If the sum is greater than zero, the pointer at the end is moved to the left. If the sum is less than zero, the pointer at the beginning is moved to the right. If the sum is equal to zero, the triplet is added to the result set. This process continues until all possible triplets are considered.

In a public key cryptography system, the key that should be made open (public) for digital signature purposes is the encryption key.

The encryption key is used to encrypt the message, which can then only be decrypted by the owner of the corresponding private decryption key. However, when using digital signatures, the message is not actually encrypted, but rather a mathematical function is applied to the message using the sender's private key. This creates a unique signature that can only be verified by the sender's corresponding public key. Therefore, the encryption key is the one that needs to be made public in order to verify the digital signature, while the private decryption key must be kept secret to maintain security.
