I meed help in this daata strutcure project$1.$ To calculate a given expression in writing $($Calculator$)$For example:When the expression $3+4-98$ is given, the program should interpret the expression as $3+4-(9*8)$ and display the result as $3+4-98=3+4-(9*8)=-65.$Additionally, when the expression cos$($P$/4)$ is given, it should calculate the result as cos$/$pl $/4)=0\mathrm{.}707106781.$The following operators must be recognised:$*$ addition $(+)*$ subtraction $(-)*$ multiplication $(*)*$ division $(/)*$ exponentiation $(^)*$ modulo $(\%)*$ factorial $(!)*$ sin$*$ COS$*$ tan$*$ cot$*$ asin$*$ acos$*$ atan$*$ acot$*$ In $($natural logarithm$)*$ log $($logarithm with base $10)*$ sgn $($sign function$)*$ PI $($pi constant$)*$ exp $($e constant$)*($and$)($parentheses$)$Note: Apart from these, characters and operators should not be used. If used, the program should produce an error. The implementation of the project may involve using a stack data structure. It is recommended to implement the project using a visual programming language $($Java$),$ but if done in a console environment$($C$),$ the screen outputs should be understandable.
