Sort colors [leetcode] scans the array once, and solves the space complexity of O (1 ).

back, and the corresponding nextpos ++ You can write it in one sentence: for (int c = A[i]; c When I = 0, nextpos is changed to {1, 1, 1}, but a [0] is changed to 2. So we need to reverse the for loop so that a [0] is still 0 for (int c = 2; c >= A[i]; c--) A[nextPos[c]++] = c; However, this loop does not run correctly, because when C = 2, a [0] is changed to 2, c -- void sortColors(int A[], int n) { int nextPos[3] = {0}; for (int i = 0; i Sort colors [leetcode]
