Prob;lem:
Given an array and a value, remove all instances of that value in place and return the new length.
The order of elements can be changed. It doesn‘t matter what you leave beyond the new length.
注意:题目要求保留移除后的结果 否则RA
class Solution {
public:
int removeElement(vector<int>& nums, int val) {
int index=0;
for(int i=0;i<nums.size();i++)
{
if(nums[i]!=val)
{
nums[index]=nums[i];
index++;
}
}
return index;
}
};
