1 test case is showing timelimit

#3

@gauravmadan583 You are using 2 loops, try doing it with a single loop.
Something like this:

dp[0]=0;dp[1]=1;dp[2]=2;dp[3]=3;dp[4]=4; //Initializing

for(lli i=5;i<=n;i++){
dp[i]=max(i,dp[i/2]+dp[i/3]+dp[i/4]);
}

#4


it is still showing timelimit in first test case

#5

Check this.
