Stores this information in a two dimensional 4× 7 array, where each row represents a different monkey and each column represents a different day of the week. First let the user input the data of food eaten by each monkey then it should create a report that includes the following information: Average amount of food eaten by each monkey for the whole week. The least amount of food eaten during the week by any one monkey.
- Write a java labguage program to use parallel arrays to save User ID and Password.

- Write a program that randomly fills in 0s and 1s into a 4-by-4 matrix, prints the matrix, and finds the first row and column with the most 1s. Here is a sample run of the program: 0011 0011 1101 1011 The largest row index: 2 The largest column index: 3Use the mabode function to create a matrix of |y| values. Although “mabode.m” is an m-file, the function is called “mabode” without the “.m”! You can pass variables to mabode the same way you would to any other function, and you can save the function’s answer – the matrix M in “mabode.m” – to a new variable. (You don’t have to call the new variable M.) 3. Create a surface plot using the input vectors and the output matrix (using the command surf).In cell C18 type a VLOOKUP function to find the corresponding letter grade (from column D) for the name in A18. The table array parameter is the same as in B18. Type FALSE for the range lookup parameter. Copy the formula in C18 to C19:C22Notice this formula works correctly for all cells. Range lookup of FALSE means do an exact match on the lookup value whether or not the table array is sorted by its first column. In cell E11, type an IF function that compares the score in B11 with the minimum score to pass in A5. If the comparison value is true, display Pass. Otherwise, display Fail. Copy the formula in E11 to E12:E15. Did you use appropriate absolute and relative references so the formula copied properly? In cell F11, type an IF function that compares the grade in D11 with the letter F (type F). If these two are not equal, display Pass. Otherwise, display Fail. Copy the formula in F11 to F12:F15
