Question

add a method named problem10 that accepts an array of integers. move all 0's to the end of an array if any. give two references, start and end, to initially point at the first and last elements in the array. page | 2 swap the elements at start and end if necessary. make them gradually meet in the middle.

Answer 1

The method problem10 moves all 0's to the end of an integer array using two references, start and end, to swap elements in the array until they meet in the middle.

Step-by-step explanation:

The correct answer is to create a method called problem10 that will manipulate an array of integers to move all 0's to the end of the array. The method will take references to the start and end indices of the array and swap elements as necessary. The swapping process moves zeros towards the end while maintaining the order of the non-zero elements. This approach is often used in problems related to array manipulation and is a common task in programming interviews.

The mechanism works by advancing the start reference when a non-zero is found, and decrementing the end reference when a zero is located. If start points to a zero and end points to a non-zero, their elements will be swapped. The process repeats until the start and end references meet in the middle, ensuring all zeros are at the end of the array with minimal element movements.
