Translate the following C program into an assembly program T

Translate the following C program into an assembly program. The C program finds the minimal value of three signed integers. Assume a, b, and c is stored in register r0, r1, and r3 respectively. The result min is saved in register r4. If (a

   MOV r0, #0xA   ;value of a load into r0

   CMP r0,r1       ; Compare value in r0 with r1   i.e a < b  
   BLT less1       ; if value of r0 < value of r1 then branch to less1 Else next instruction

   CMP r1,r0       ;compare value in r1 with r0 i.e b < a
