Slip No.4

1) Write an R program to extract first 10 English letter in lower case and last 10 letters in upper case and extract letters between 22nd to 24th letters in upper case.

# Define the vector of English letters
letters_lower <- letters # Lower case letters
letters_upper <- LETTERS # Upper case letters

# Extract the first 10 English letters in lower case
first_10_lower <- letters_lower[1:10]

# Extract the last 10 English letters in upper case
last_10_upper <- letters_upper[(length(letters_upper) - 9):length(letters_upper)]

# Extract the letters between the 22nd and 24th letters in upper case
letters_22_to_24_upper <- letters_upper[22:24]

# Print the results
cat("First 10 letters in l_case: ", first_10_lower, "\n")
cat("Last 10 letters in u_case: ", last_10_upper, "\n")
cat("22nd to 24th in upper case: ", letters_22_to_24_upper, "\n")
