Radioactive decay of radioactive materials can be modeled by the equation
A=A0e–t(In2/h), where
A is the amount of the material at time t, A0 is the amount at time 0, and h is the half-life.
Technetium-99 is a radioisotope that is used in imaging of the brain. It has a half-life of 6 hours.
Your program should display the relative amount A/A0 in a patient body every hour for 24 hours after receiving a dose.
Note:
With the aid of formatting techniques documented in your note, ensure your program output matches that given below.

write a program to read the mobile number in human form. The 10 digit mobile number should be divide into 4-3-3 format . If it has continues 4 numbers it should be pronounced as quadruple , 3 numbers as thriple , 2 numbers as double.
input:- 9977222208
Here system should divide itself in 4-3-3 format like 9977 222 208
output: double nine double seven thriple two two zero eight
input:- 1111999228
output:- quadruple one thriple nine double two eight
given a sentence , swap the occurrences of the most frequent letter which the least frequent letter and vice-versa. note : .consider upper and lower case letters as different. if there are multiple letters with the same frequency , choose the lowercase letters that comes earliest in dictionary order. if letter like S and B have same frequency consider X. if letter like X and b have same frequency consider b.?
in the example the sentence is Nice Day.
the previous letter of N is M, similarly replace each letter with the previous letter
N i c e D a y
M h b d C z x
so the output should be Mhbd Czx
sample input 1
Nice Day
sample output 1
Mhbd Czx
sample input2
Be good and do good
sample output2
Ad fnnc zmc cn fnnc
in the example there are 6 numbers 1,-2,3,-4,-5,6
the negative numbers in the given list are -2,-4 and -5 where the -2 is replaced with corresponding last positive number encountered which is 1.similarly -4 and -5 are replaced with 3
so the output should be 1 1 3 3 3 6
sample input1
1 -2 3 -4 -5 6
sample output1
1 1 3 3 3 6
sample input2
1 11 -13 21 -19
sample output2
1 11 11 21 21
Yup are given a space separated list of integers as input,write a program to replace all non positive numbers in a list with the last positive number encountered
program to find sum of non-diagonal elements of matrix of MxM
Input:
3
9 8 7
6 5 4
3 2 1
Output: 20
in the example the first test case number is 9966777819 and this number should be divided into 4 3 3 format
the first divided part should be read a double nine double six. As there are two consecutive 9's,it should be read as double nine.similarly there are two consecutive 6's it should be read as double six
in the second divided part there are three consecutive 7's it should be read as triple seven.
In the third divided part there are no consecutive digits each digit should be read separately.
sample input1
9966777819
sample output1
double nine double six triple seven eight one nine
sample input 2
7299613014
sample output 2
seven two double nine six one three zero one four
You are given a sentence Nice day Write a program to replace each letter with the previous letter in the english alphabet
You are given a string containing ten digits, write a program to print these digits in a human readable format.
There are some rules to how to read a number,
1. Divide the ten digit number into set of four-three-three digits
2.use the following prefixes for consecutive digits
# Single numbers just read them seperately
# 2 successive numbers use double
# 3 successive numbers use triple
# 4 successive numbers use quadruple
