简单模拟
根据题目描述,简单的模拟一遍即可。
class Solution {
public String countAndSay(int n) {
StringBuilder sb = new StringBuilder("1");
for (int k = 1; k < n; k++) {
StringBuilder temp = new StringBuilder();
int i = 0, j = 0;
while (i < sb.length()) {
while (j < sb.length()) {
if (sb.charAt(i) != sb.charAt(j)) break;
j++;
}
temp.append(j - i);
temp.append(sb.charAt(i));
i = j;
}
sb = temp;
}
return sb.toString();
}
}
