Remove Element
Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The relative order of the elements may be changed.
Example 1:
Input: nums = [3,2,2,3], val = 3
Output: 2, nums = [2,2,_,_]
Example 2:
Input: nums = [0,1,2,2,3,0,4,2], val = 2
Output: 5, nums = [0,1,4,0,3,_,_,_]
class Solution {
public int removeElement(int[] nums, int val) {
int count=nums.length;
int i=0;
for(int j=0;j<count;j++)
{
if(nums[j]!=val)
{
nums[i]=nums[j];
i++;
}
}
return i;
}
}
