Largest Number between two numbers

Back to Programming

Description

The program is written to find the largest number between two given numbers. The two numbers are taken as inputs from the user and then the values are compared and the largest value is printed.

If the two numbers are 5 and 10, then the largest number is 10 which will be displayed as output.

Algorithm

INPUT: Two numbers

OUTPUT: Largest number

PROCESS:

Step 1: [Taking the inputs]

               Read a, b [two numbers]

Step 2: [Finding the largest number]

               If a>b then

                              Print “a is largest”

               Else

                              Print “b is largest”

               [End of ‘if’]

Step 3: Stop.

Code

TIME COMPLEXITY:

if(a>b)----------------------------------O(1)

                              printf("%d is largest",a);

               else--------------------------------------O(1)

                              printf("%d is largest",b);

The time complexity of this program is O(1) means it requires a constant time to execute this program.

SPACE COMPLEXITY:

The space complexity of this program is O(1) as it requires a constant number of spaces for any given input.
