题目: Given an array and a value, remove all instances of that value in place and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. The order of elements can be changed. It doesn't matter what you leave beyond the n...

Do not allocate extra space for another array, you must do this bymodifying the input array in-placewith O(1) extra memory. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 示例1:
It is possible to delete list elements with remove, pop, and clear functions and the del keyword. Python list removeThe remove function removes the first occurrence of the given value. It raises ValueError if the value is not present.
add the a[n-1] element into res array We will print the elements present in the index range from i=0 to i=k-1 before returning the value of k, which is now the total number of unique elements in the array. Code Implementation C++ Java Python #include<bits/stdc++.h> using namesp...
