Count elements in first Array with absolute difference greater than K with an element in second Array code example
Example 1: how to sort a list by the second element in tuple python
def sort_prices(list_of_tuples):
list_of_tuples.sort(key=lambda x: x[1], reverse=True)
return list_of_tuples, print(list_of_tuples)
Example 2: count number of times an element is occuring in an array in javascript
Array.prototype.frequencies = function() {
var l = this.length, result = {all:[]};
while (l--){
result[this[l]] = result[this[l]] ? ++result[this[l]] : 1;
}
// all pairs (label, frequencies) to an array of arrays(2)
for (var l in result){
if (result.hasOwnProperty(l) && l !== 'all'){
result.all.push([ l,result[l] ]);
}
}
return result;
};
var freqs = [5, 5, 5, 2, 2, 2, 2, 2, 9, 4].frequencies();
alert(freqs[2]); //=> 5
// or
var freqs = '1,1,2,one,one,2,2,22,three,four,five,three,three,five'
.split(',')
.frequencies();
alert(freqs.three); //=> 3
Example 3: Return the number of elements in this RDD.
sc.parallelize([2, 3, 4]).count()
