C++ Function to Remove Elements from an Array: int removeElement(int* nums, int numsSize, int val)

This function takes in an array of integers, its size, and a value to be removed. The function then iterates through the array, checking if each element is equal to the value to be removed. If not, the element is copied to a new position in the array indicated by a variable 'k'. The function then returns 'k', which represents the new size of the array after removing all occurrences of the specified value.
