2325. Decrypt

Thought：

Simple hash mapping table，pythonUse ascii_lowercase[] Directly obtain a lowercase letter。
Golang Look at the answer of Lingshen，

“Imam on the space to the space，In this way, you don’t need to judge the space。”

Code：

python

from string import ascii_lowercase

class Solution:
    def decodeMessage(self, key: str, message: str) -> str:
        str1 = ''
        dict1 = {}
        index = 0
        for i in key.replace(' ', ''):
            if i not in dict1:
                dict1[i] = ascii_lowercase[index]
                index += 1
        for i in message:
            if i in dict1:
                str1 += dict1[i]
            else:
                str1 += ' '
        return str1

golang

func decodeMessage(key string, message string) string {
	mp := ['z' + 1]byte{' ': ' '}
	cur := byte('a')
	for _, c := range key {
		if mp[c] == 0 {
			mp[c] = cur
			cur += 1
		}
	}
	s := []byte(message)
	for i, c := range s {
		s[i] = mp[c]
	}
	return string(s)
}
