import sys

a=input()
b=input()
str1=dict()
str2=dict()
for x in a:
    str1[x]=str1.get(x, 0)+1
for x in b:
    str2[x]=str2.get(x, 0)+1

for i in str1.keys():
    if i in str2.keys():
        if str1[i]!=str2[i]:
            print("NO")
            break
    else:
        print("NO")
        break
else:
    print("YES")

<개선된 코드>
import sys
#sys.stdin=open("in1.txt", "r")
a=input()
b=input()
sH=dict()
for x in a:
    sH[x]=sH.get(x, 0)+1
for x in b:
    sH[x]=sH.get(x, 0)-1

for x in a:
    if(sH.get(x)>0):
        print("NO")
        break;
else:
    print("YES")

差異

if x in firstDic:
    firstDic[x] += 1
else:
    firstDic[x] = 1

str1[x]=str1.get(x, 0)+1
