Remove Element
Understand how to apply the two pointers technique to remove specific elements from an array without extra memory. This lesson helps you solve a common coding interview problem by modifying the array in place and returning the count of remaining elements, enhancing your skills in problem-solving and efficient array manipulation.
We'll cover the following...
Statement
You are given an integer array, nums, and an integer, val. Your task is to remove all occurrences of val from nums in place, meaning no additional memory allocation should be used. The relative order of the elements in the array may be changed. After modifying the array, return the number of elements that are not equal to val.
Let nums that are not equal to val. To successfully solve this problem, you need to ensure the following:
Modify the array,
nums, such that the first...
