+get the random number guessed by the computer by passing the lower,higher
+and the number to guess
+
+this solution works on divide and getting the half of number of previous and
+current, this depends on the number is low or high
+
+if the number is more than last lower and less than to the number to guess then
+the number is assigned to it, and same but opposite for higher number
+
+suppose lower is 0, higher is 1000 and the number to guess is 355
+then:
+    num = int((lower+higher)/2)
+    for above statement the function already declared as the get_avg(a,b)
+
+        [1]
+    get_avg(0,1000)  : 500
+    answer(500) : high
+        Now this value is passed to the answer function and that returns the
+        passed number is lower than the guess number or higher than the guess
+        number and also for equality
+
+        [2]
+    get_avg(0,500) : 250
+    answer(250) : low
+
+        [3]
+    get_avg(250,500) : 375
+    answer(375) : high
+
+        [4]
+    get_avg(375,250) : 312
+    answer(312) : low
+
+        [5]
+    get_avg(312,375) : 343
+    answer(343) : low
+
+        [6]
+    get_avg(343,375) : 359
+    answer(359) : high
