Exponential without function
Back to ProgrammingDescription
The program is written to find the exponent of a number without using the inbuilt function. The number and the exponent are taken as input. The numbers are multiplied exponential time to get the value.
For example, the given number is 2 and the exponent is 5, therefore, 2 will be multiplied 5 times.
The value will be: 2×2×2×2×2 = 32
Algorithm
INPUT: The number and the exponent
OUTPUT: The exponential value of the number
PROCESS:
Step 1: [Taking the input]
Read n [The number]
Read exp [the exponent]
Step 2: [Finding the exponential]
Set e<-1
[Finding the exponential]
While exp!=0 repeat
Set e<-e×n
Set exp<-exp-1
[End of ‘while’ loop]
[Displaying the value]
Print "The result is: e"
Step 3: Stop.
Code
TIME COMPLEXITY:
while(exp!=0)----------------------------------O(m)
{
e=e*n;
exp--;
}
The time complexity of this program is O(m) where ‘m’ is the exponent.
SPACE COMPLEXITY:
The space complexity of this program is O(1) as it requires a constant number of memory spaces for any given input.
