[ad_1] You need two loops – one nested within another. One to print the rows and another to print the numbers within the rows. The range of the first loop is pretty straight forward, but the range of the nested loop will depend on the parent loop. For Python 3.x: for i in range(1,11): for … Read more
[ad_1] They are different first of all. for-each uses Iterator under the hood whereas for is useful for operations on arrays or where you can do something meaningful with indexes. [ad_2] solved What is very faster, normal for loop or foreach loop in java? [duplicate]
[ad_1] Is this ok ? >>> def containsLetter(searchLetter, hulkLine): … return [x for x in hulkLine if searchLetter in x] … >>> containsLetter(‘i’, hulkLine) [‘like’, “i’m”] >>> Or >>> filter(lambda x: searchLetter in x, hulkLine) [‘like’, “i’m”] >>> 4 [ad_2] solved Write a function named containsLetter that identifies all of the strings in a list … Read more
[ad_1] First for-loop fills an array of length x with user entered values. Second for-loop checks for array like this [1,2,3,3,2,1]. So it checks wether the array is reversev in the second half. Though because of the return the for-loop will be canceled at first run. So if the first entry of the array equals … Read more
[ad_1] var count_br = “4,7,10”; var count_ = count_br.split(“,”); var i; for (i = 0; i < count_.length; ++i) { for(let idx in count_) count_[idx] = (parseInt(count_[idx])+4).toString() } console.log(count_) [ad_2] solved Increment all values of [closed]
[ad_1] Use a dictionary: >>> x=[‘a’, ‘b’, ‘c’, ‘d’] >>> di={k:[] for k in x} 1 [ad_2] solved How to make several list which have a name already decided variable [closed]
[ad_1] Because for-loop needs 3 parameters. If you just give 2 parameters with 3rd parameter not being given, compiler expects the loop variant parameter there. Usually – for(iteration variable; condition; increment/decrement ) for(;condition;increment/decrement ){} for(iteration variable;;increment/decrement) {} for(;;increment/decrement) {} … 1 [ad_2] solved This just bugs me [closed]
[ad_1] The condition i==j+1 will not be true for i==2. This can be fixed by a couple of changes to the inner loop: #include <stdio.h> int main(void) { for (int i=2; i<100; i++) { for (int j=2; j<=i; j++) // Changed upper bound { if (i == j) // Changed condition and reversed order of … Read more
[ad_1] Try: String s = “”; for(int i = 0 ; i < nLines ; ++i) { s = (i % 2 == 0 ? “1 ” : “0 “) + s; System.out.println(s); } [ad_2] solved Create triangle with “1” ” 0″ by for loop [closed]
[ad_1] for(int i = 0; // i is an variable integer, which is 0 from the start i < 10; // if i is 10 or above, the loop is finished, else the code runs i += 2) // after the code is ran, 2 will be added to the variable i {/*…*/} [ad_2] solved … Read more
[ad_1] //if you’re using Eclipse, press ctrl-shift-f to “beautify” your code and make it easier to read int arr[] = new int[3]; //create a new array containing 3 elements for (int i = 0; i < 3; i++) { arr[i] = i;//assign each successive value of i to an entry in the array } int … Read more
[ad_1] The below code can be an alternative to a for loop. You just need to take care of all parts like initialization, condition, iteration count, etc. int i=0; abc: i++; if(i<10){ printf(“i is %d\n”, i); goto abc; } When a for loop is compiled, the assembler uses goto-like statements to generate assembly code for … Read more
[ad_1] I am trying to write an encryption in Python. My Problem is that the key is shorter than the message. Therefore I should start again with the key [ad_2] solved I am trying to write an encryption in Python. My Problem is that the key is shorter than the message. Therefore I should start … Read more
[ad_1] You need to set a CursorPosition to a given location, then need to draw a horizontal line. Like, public static void LineHorizontale(int x, int y, int length) { //This will set your cursor position on x and y Console.SetCursorPosition(x, y); //This will draw ‘-‘ n times here n is length Console.WriteLine(new String(‘-‘, length)); } … Read more
[ad_1] Please note, the third for loop is nested inside the second loop. So, for each value of j in the other loop body like 0, 1, 2, the inner loop will execute for each time. If you’re bothered that after the first loop, j will be 10, then don’t worry, the statement-1 in the … Read more
