Easy
10m average time
0/40
Asked in companies
You are given two numbers 'a' and 'b' as input.
You must swap the values of 'a' and 'b'.
For Example:
Input:
'a' = 8, 'b' = 5
Output:
5 8
Explanation:
Initially, the value of 'a' and 'b' is 8 and 5, respectively.
After swapping, the value of 'a' is 5, and the value of 'b' is 8.
Problem approach
ENTER x, y
PRINT x, y
x = x + y
y= x - y
x =x - y
PRINT x, y

Asked in companies
Bubble Sort is one of the sorting algorithms that works by repeatedly swapping the adjacent elements of the array if they are not in sorted order.
You are given an unsorted array consisting of N non-negative integers. Your task is to sort the array in non-decreasing order using the Bubble Sort algorithm.
For Example:
Bubble Sort implementation for the given array: {6,2,8,4,10} is shown below :-
Problem approach
for i <- 1 to indexOfLastUnsortedElement-1
if leftElement > rightElement
swap leftElement and rightElement
