Write a program that: 1) Prompt the user to enter a file name to save the inputs. 2) Prompt the user to enter information/statements. 3) Save the information/statements entered by user to the file name given early. 4) Close the file. 5) Reopen the input file 6) Read all info from the file. 7) Reverse all characters from the reading. 8) Prompt the user to enter a file name to save the outputs. 9) Write the reversed results to the file. Do not use reverse function provided in the algorithm header file. Suppose the user specifies input.txt and output.txt when prompted for the file names, and input.txt contains the lines Mary had a little lamb Its fleece was white as snow And everywhere that Mary went the lamb was sure to go. After the program is finished, output.txt should contain bmal elttil a dah yram wons sa etihw saw eceelf sti tnew yram taht erenwyreve dnA og ot erus saw bmal eht
