【leetcode】Interleaving String
Interleaving String
Given s1, s2, s3, find whether s3 is formed by the interleaving of s1 and s2.
For example,
Given:
s1 = "aabcc",
s2 = "dbbca",
When s3 = "aadbbcbcac", return true.
When s3 = "aadbbbaccc", return false.
class Solution {
public:
bool isInterleave(string s1, string s2, string s3) {
int n1=s1.length();
int n2=s2.length();
int n3=s3.length();
if(n1+n2!=n3)
{
return false;
}
vector<vector<bool> > dp(n1+,vector<bool>(n2+,false));
dp[][]=true;
for(int i=;i<=n1;i++)
{
dp[i][]=dp[i-][]&&s1[i-]==s3[i-];
}
for(int j=;j<=n2;j++)
{
dp[][j]=dp[][j-]&&s2[j-]==s3[j-];
}
for(int i=;i<=n1;i++)
{
for(int j=;j<=n2;j++)
{
dp[i][j]=(dp[i-][j]&&s1[i-]==s3[i+j-])||(dp[i][j-]&&s2[j-]==s3[i+j-]);
}
}
return dp[n1][n2];
}
};
