sizeof(array)/sizeof(array[0]) _countof(array) These tell you thesize (capacity)of the array, i.e. how muchstorage spacethere is in the array. They donottell you anything about the currentcontentof the array! Specifically, they donottell you the "length" of the string, i.e. how ...

You may assume no duplicate exists in the array. 解题思路: 最朴素的O(n)的方法,就是找到突然变小的那个元素,肯定是最小的。否则就说明所有元素一直变大,本来就是排序的,则返回第一个元素。 publicclassSolution {publicintfindMin(int[] num) {if(num.length == 0){return0; ...
