Remove Element

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.

//在数组中移除指定的value，不能新建数组，返回新的数组长度

//此题very easy，代码如下：
int RemoveElement(int A[],int n, int elem)
{
	int i=0,j=0;//定义两个游标指向数组第一个元素
	for (i=0; i<n; i++)
	{
		if (A[i]==elem)
		{
			continue;
		}
		A[j++]=A[i];
	}
	return j;
}
