Calculate average from a given set of keys and values
Hello,
I am writing a script which expects as its input a hash with student names as the keys and marks as the values. The script then returns array of average marks for student scored 60-70, 70-80, and over 90.
Output expected
The test script so far I have written looks like this
I am able to store the input as hash with keys and its values but not able to calculate the average and give the output as expected. Any suggestions would be appreciated.

Hello,
I'm hoping to get some help on calculating an average time from a list of times (hour:minute:second).

lh_node_stats_bio
lh_stats(3) OpenSSL lh_stats(3)NAME
lh_stats, lh_node_stats, lh_node_usage_stats, lh_stats_bio, lh_node_stats_bio, lh_node_usage_stats_bio - LHASH statistics
SYNOPSIS
#include <openssl/lhash.h>
void lh_stats(LHASH *table, FILE *out);
void lh_node_stats(LHASH *table, FILE *out);
void lh_node_usage_stats(LHASH *table, FILE *out);
void lh_stats_bio(LHASH *table, BIO *out);
void lh_node_stats_bio(LHASH *table, BIO *out);
void lh_node_usage_stats_bio(LHASH *table, BIO *out);
DESCRIPTION
The LHASH structure records statistics about most aspects of accessing the hash table. This is mostly a legacy of Eric Young writing this
library for the reasons of implementing what looked like a nice algorithm rather than for a particular software product.
lh_stats() prints out statistics on the size of the hash table, how many entries are in it, and the number and result of calls to the
routines in this library.
lh_node_stats() prints the number of entries for each 'bucket' in the hash table.
lh_node_usage_stats() prints out a short summary of the state of the hash table. It prints the 'load' and the 'actual load'. The load is
the average number of data items per 'bucket' in the hash table. The 'actual load' is the average number of items per 'bucket', but only
for buckets which contain entries. So the 'actual load' is the average number of searches that will need to find an item in the hash
table, while the 'load' is the average number that will be done to record a miss.
lh_stats_bio(), lh_node_stats_bio() and lh_node_usage_stats_bio() are the same as the above, except that the output goes to a BIO.
RETURN VALUES
These functions do not return values.
