The elements returned by the hash function are called simply hash, hash codes, hash values, or digests. To find the largest element, the first two elements of array are checked and the largest of these two elements are placed in arr[0] the first and third elements are checked and largest of these two elements is placed in arr[0]. Elements can be removed from an array by removing a specific element of the array, a range of elements in the array, the first element of the array, or the last element of the array.
