Convert List<Long> to Map<Long, Long> that counts occurrences
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further I'm playing around with Java 8 and I know that this must be possible by reading the documentation, I just cannot find out how to do it. , If you want to group the elements, you have to use groupingBy: import static java.util.stream.Collectors.*;
Map<Long, Long> primeFactorCount = primeFactors.stream()
.collect(groupingBy(p -> p, counting()));

How would I subtract milliseconds from long year, long month, long day, long hour, and long minute?
Date : March 29 2020, 07:55 AM
This might help you I had to do something similar and came to realize that Java's Date class is shit. Luckily someone really kind out there made an amazing library called JodaTime. Here is the android version: https://github.com/dlew/joda-time-androidWith JodaTime you can do something like this: date.minusMinutes(1);//this subtracts a minute from your date time variable
date.plusHours(3);//adds 3 hours
date.before(anotherDate);//checks if date is earlier in time than anotherDate

Tag : c , By : Gerhard Miller
Date : March 29 2020, 07:55 AM
wish of those help I have written two functions to find power of positive and negative number in c but it is not printing anything , You're not actually calling the functions: if(number<0)
{
void Calculate_neg_power(number,expo);
}
else{
void Calculate_pos_power(number,expo);
}
if(number<0)
{
Calculate_neg_power(number,expo);
}
else{
Calculate_pos_power(number,expo);
}
int Driver(NUMBER,EXPO, ans);

map(long long int,long long int) not working for key=1000 000 000(in range of long long int )
Date : March 29 2020, 07:55 AM
wish help you to fix your issue First, this is bad: #include If you need map, use:#include <map>
#include <iostream>
#include <map>
int64_t exchange(std::map& <int64_t, int64_t>, int64_t n){
if(n<12)
return n;
if(dp.count(n))
return dp[n];
return dp[n] = exchange(n/2)+exchange(n/3)+exchange(n/4);
}
int main(){
std::map <int64_t, int64_t> dp;
while(1){
int64_t n;
std::cin>>n;
std::cout<<exchange(dp, n)<<std::endl;
}
}
