Please write in C language. This program requires me to use the malloc$()$ function. Thank you!

Problem: Given an integer to serve as a seed for the random number generator, the desired data set size $($minimum of ten$),$and the maximum value to generate $($minimum is one$),$complete the creation of the described data set and calculate the median value and the sample standard deviation. The next step is to modify each integer in the data set as follows, compare the digit at the lowest power of ten with the digit at the highest power of ten and exchange them when the digit at the lower power of ten is greater than that at the higher power of ten. Continue next comparing the digit at the second highest power of ten with the digit at the second lowest power of ten making an exchange of digits when the digit at the lower power of ten is larger than that at the higher power of ten. This process continues through all digits in each number. Example modification #$1$: $13478526$ would result in $63587421,$ three exchanges are made $(16,45,78).$ Example modification #$2$: $4235780$ would result in $4875320,$ two exchanges are made $(28,37).$ Calculate the median value and the sample standard deviation again for the modified data set.
