What is the time complexity for a while loop?
Each iteration in the while loop, either one or both indexes move toward each other. In the worst case, only one index moves toward each other at any time. The loop iterates n-1 times, but the time complexity of the entire algorithm is O(n log n) due to sorting.
How many times will the following loop execute for J 1 J <= 10 J J 1 * 1 point?
1 Answer. and so on , there is no stopping of the loop , as the base condition for j<=10 will always be true .
How many times the loop for i 1 i ni i * 2 will execute?
so it will go for infinite loop. Outer loop works O(log(n)) times and inner loop works O(n) times. So,time complexity will be O(nlogn) base 2. j is starting at 1, and doubling at every iterating.
What is the time complexity of the following code function for i 1?
Let W(n) and A(n) denote respectively, the worst case and average case running time of an algorithm executed on an input of size n….
| Code | Time complexity |
|---|---|
| for (i=1; I <= n; i*=2) | O(logn) because I is incremented exponentially and loop will run for less number of times than n. |
Is a while loop O 1?
The inner for loop iterates O(N) times, for each iteration of the for loop. The outer for loop only does O(1) work, other than the inner for loop.
How many times will the following loop execute for J is equals to 1?
3 times will the loop execute.
How many times will the following loop execute *?
Following loops will execute 3 times. Loop 1 is Entry control loop and Loop 2 is Exit control loop.
How many loops do you make before you can proceed to C?
We have three types of loops in C. The working of these loops are almost similar, however they are being used in different scenarios. You may need to choose the loop based on the requirement. Below are the tutorial links on each type of loop (for, while, do-while) & loop control statements(break, continue, goto).
What is the time complexity of this simple loop?
Time complexity of a simple loop when the loop variable is incremented or decremented by a constant amount: Here, i: It is a loop variable. n: Number of times the loop is to be executed. In above scenario, loop is executed ‘n’ times. Therefore, time complexity of this loop is O (n).
How many times does the loop execute?
The loop will execute for infinite number of times mate. Because each time the value of j reduces by one and that satisfies the condition that j <= 10; It is an endless loop, because your initial condition is j = 1, and j should be less than equal to 10, this condition is true, hence loop runs like this:
How to count the number of times a particular line is executed?
When we analyze an algorithm, we count how many times a particular (important) line is executed. Example: 1. fori := 1 ton do2. forj := 1 ton do3. x := x + 1 // count this line The number of times the line 3 is executed when the input size was n:
How many iterations does a Java program run?
Depending on whether j is signed or unsigned, and depending on whether j is 8, 16, 32, or 64 bits wide, this loop could run anywhere from 2 iterations to about 4 billion iterations. The following program, for example, will run exactly 130 iterations. (Can you see why?
