nested-loops

I have a nested foreach loop in knockout.js and I want to access a property from the current object in the outer loop inside the inner loop. How would I do this? <!-- ko foreach: graduationDateRows --> <tr> <td class="center" data-bind="text: CalendarYear"></td> <!-- ko foreach: $root.graduationDatesHeaders --> <td class="center" data-bind="text: /* !here! */"></td> <td></td> <!-- /ko --> </tr> <!-- /ko --> You can use $parent to access one scope level up. So, from your inner loop you can use parent to access the current item being looped on in your graduationDateRows Stas Slabko You can even

I want to write a nested for loop that has to work in the bash shell prompt. nested for loop in Single line command. For example, for i in a b; do echo $i; done a b In the above example, for loop is executed in a single line command right. Like this I have tried the nested for loop in the shell prompt. Its not working. How to do this. Please update me on this. This is not a nested loop, just a single loop. And the nested version works, too: # for i in a b; do for j in a b; do echo $j; done; done a b a b One one line (semi-colons necessary): for i in 0 1 2 3 4 5 6 7 8 9; do for j in 0 1 2 3 4 5

This question already has an answer here: How do I break out of nested loops in Java? 35 answers I have been using Java for quite some time, yet my education in loops is somewhat lacking. I know how to create every loop that exists in java and break out of the loops as well. However, I've recently thought about this: Say I have two nested loops. Could I break out of both loops using just one break statement? Here is what I have so far. int points = 0; int goal = 100; while (goal <= 100) { for (int i = 0; i < goal; i++) { if (points > 50) { break; // For loop ends, but the while loop does not }

This question already has an answer here: Why does the order of the loops affect performance when iterating over a 2D array? 7 answers I was going through loops and found a significant difference in accessing loops. I can't understand what is the thing that causes such difference in both cases? First Example: Execution Time; 8 seconds for (int kk = 0; kk < 1000; kk++) { sum = 0; for (int i = 0; i < 1024; i++) for (int j = 0; j < 1024; j++) { sum += matrix[i][j]; } } Second Example: Execution Time: 23 seconds for (int kk = 0; kk < 1000; kk++) { sum = 0; for (int i = 0; i < 1024; i++) for (int j

This has to be easier than what I am running into. My problem is turning a string that looks like this: ABC12DEF3G56HIJ7 into 12 * ABC 3 * DEF 56 * G 7 * HIJ And I can't, for the life of me, design a correct set of loops using REGEX matching. The crux of the issue is that the code has to be completely general because I cannot assume how long the [A-Z] fragments will be, nor how long the [0-9] fragments will be. Thank you for any assistance! Ray Toal Python's re.findall should work for you. Live demo import re s = "ABC12DEF3G56HIJ7" pattern = re.compile(r'([A-Z]+)([0-9]+)') for (letters,

This question already has an answer here: JavaScript - retrieve value from nested object, using array of keys 1 answer If this is my object: var obj = { bakery1: { small: { name: "Small cookie", price: 0.75; } large: { name: "Large cookie", price: 3.00; } } bakery2: { small: { name: "Small cookie", price: 1.00; } large: { name: "Large cookie", price: 4.00; } } }; How would I go about making a loop that prints every price to the console? And when this value is printed, is there a way to trace the name? For example if the output is 3.00 how would I make a function that gives me the name that
