You must do this in-place without making a copy of the array. Minimize the total number of operations. Credits: Special thanks to@jianchao.li.fighterfor adding this problem and creating all test cases. 1publicclassSolution {2publicvoidmoveZeroes(int[] nums) {3intpos = 0;4for(inti =0; ...
Could you do it in one-pass, using only O(1) extra memory and without modifying the value of the board? 【解答】要数有多少 battleship,并且要求使用 O(1) 的空间复杂度,还不能修改 board 上的数值。 一行一行遍历,每一行中从左往右遍历。对于每一个点,如果左侧和上方都不是 X,那就...
