topic

Given two strings s1 and s2, Please write a program , After determining the character rearrangement of one of the strings , Can it be another string .

Example 1：

Input : s1 = “abc”, s2 = “bca”
Output : true
Example 2：

Input : s1 = “abc”, s2 = “bad”
Output : false
explain ：

0 <= len(s1) <= 100
0 <= len(s2) <= 100

answer

class Solution {
    
    public boolean CheckPermutation(String s1, String s2) {
    
         char[] c1=s1.toCharArray();
        char[] c2=s2.toCharArray();
        if(c1.length!=c2.length) return false;
        boolean a=false;
        boolean b=false;
        int j=0;
        for(int i=0;i<c1.length;i++)
        {
    
            for(j=0;j<c2.length;j++)
            {
    
                if(c1[i]==c2[j]) break;

            }
            if(j==c2.length) return false;
            j=0;
        }
        a=true;
        for(int i=0;i<c2.length;i++)
        {
    
            for(j=0;j<c1.length;j++)
            {
    
                if(c2[i]==c1[j]) break;

            }
            if(j==c2.length) return false;
            j=0;
        }
        b=true;
        return a&&b;
    }
}
