On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements.
Implement the counter increment, and branch back to the start of the loop. When you havecompleted these steps, the basic structure of the counter control loop has been implemented,and your code should look similar to the following:.text li $s0, 0 lw $s1, n start_loop: sle $t1, $s0, $s1 beqz $t1, end_loop # code block addi $s0, $s0, 1 b start_loop end_loop:.data n: .word 5
write in assembly language usinf LC3 simulator LC3 simulator to use: https://wchargin.com/lc3web/ Implement an if-else statementa. An if-else statement will execute one out of two blocks of codeb. Your if-else statement should check if R0 = R1, then make R3 = 5, if R0 ≠ R1, then make R3 = -5c. You can manually modify R0, R1, and R3, in the simulator (before running your program only). You do nothave to program values for these registers Psuedo code: .ORIG x3000 ; Two's Complement R1 (two instructions: negate and add 1) ; Initialize R3 with #0 ; Add R0 and R1; place result into R2 (are they equal? If they are, what value is in R2?) ; Branch if non-zero to ELSE (they are not equal in this case) IF ; Place #5 in R3 ; Branch to done ELSE ; Place #-5 in R3 DONE ; Halt CPU .END

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to compute r = 2(1/12) using the pow function (remember to include the cmath library). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4.
