问题 Basically i have two files with strings in them separated with a new line. What i wish to do is get the first string from the first file and compare it to ALL of the strings from the second file. Then get the second string from the first file and compare it to ALL of the strings in the second file then get the third and etc etc. Currently i have this piece of code, but i am not sure if it is working as i wish it to be $file = file_get_contents("file1.txt"); $pieces = explode("\n", trim($file)

Comparing two RDDs

由 喜夏-厌秋 提交于 2019-12-02 08:44:43
I have two RDD[Array[String]], let's call them rdd1 and rdd2. I would create a new RDD containing just the entries of rdd2 not in rdd1 (based on a key). I use Spark on Scala via Intellij. I grouped rdd1 and rdd2 by a key (I will compare just the keys of the two rdds): val rdd1Grouped = rdd1.groupBy(line => line(0)) val rdd2Grouped = rdd2.groupBy(line => line(0)) Then, I used a leftOuterJoin : val output = rdd1Grouped.leftOuterJoin(rdd2Grouped).collect { case (k, (v, None)) => (k, v) } but this doesn't seem to give the correct result. What's wrong with it? Any suggests? Example of RDDS (every

I have a file and I want to read this file using C program using file operations. Then i want to take parameters from that file. Lets say nalu_type=x. So whenever i detect the string nalu_type in that file I want to put the value x in an array which is defined by me. please tell me how to do it. Thanks in Advance Sanket If the format is nalu_type = x fscanf(fp, "%s", buf); if !strcmp(buf, "nalu_type") { fscanf(fp, "%s", buf); if ( ! strcmp(buf, "=")) fscanf(fp, "%s", buf); else printf("\n Not a valid format"); } Repeat the above if until end of file. # include<stdio.h> # include <conio.h> #

Comparing arrays of different sizes without any loop

由 北城以北 提交于 2019-12-02 08:09:25
问题 The question goes like this: Given two arrays, a & b (both with positive integers). A special number is a number which a(i) == i (the value equals to the index). How can you check if array b contains a value which is a special number of a . For example: a = [9 9 3 9] , b = [3 4 5] . Output will be 3 . If b or a are empty, output is 0 . If b contains several special number , only the smallest one will be shown. This is what I have managed to do by far, can't progress from here.. a = input(

What is the right way of comparing two lists in TCL?

由 对着背影说爱祢 提交于 2019-12-02 07:25:27
I am newbie to TCL and I have written the following code: set list1 {{1 2} 3 4} set list2 {{1 2} 8 1} if {[lindex $list1 0] == [lindex $list2 0]} { puts "They are equal!"} But when I print the sublist elements I see that they are equal, but the if statement does not catch it. Why? How I should right this comparision? If I were to implement an lequal proc, I'd start with this: proc lequal {l1 l2} { foreach elem $l1 { if {$elem ni $l2} {return false} } foreach elem $l2 { if {$elem ni $l1} {return false} } return true } And then optimize to this: proc K {a b} {return $a} proc lequal {l1 l2} { if
