【小米oj】 构建短字符串

 1 #define mm(a) memset(a,0,sizeof(a));
 2 #define max(x,y) (x)>(y)?(x):(y)
 3 #define min(x,y) (x)<(y)?(x):(y)
 4 #define Fopen freopen("1.in","r",stdin); freopen("m.out","w",stdout);
 5 #define rep(i,a,b) for(ll i=(a);i<=(b);i++)
 6 #define per(i,b,a) for(ll i=(b);i>=(a);i--)
 7 #include<bits/stdc++.h>
 8 typedef long long ll;
 9 #define PII pair<ll,ll>
10 using namespace std;
11 const int INF=0x3f3f3f3f;
12 const int MAXN=(int)2e6+5;
13 
14 char s[MAXN];
15 int a[26],b[26];
16 int main()
17 {
18     scanf("%s",s);
19     for(int i=0;s[i];i++)a[s[i]-'a']++;
20     scanf("%s",s);
21     for(int i=0;s[i];i++)b[s[i]-'a']++;
22     for(int i=0;i<26;i++)if(a[i]>b[i])return printf("false\n");
23     printf("true\n");
24     return 0;
25 }
