You need to learn how to debug your code. If you can’t do that with a debugger, write a function which prints to the screen the relevant information, such as the following:<\/p>\n

void paxDebug(const char *desc, ll arr[], ll sz, ll n, ll b, ll x, ll pos) {\n    cout << desc << \"\\n\";\n    cout << \"n = \" << n << \" b = \" << b << \" x = \" << x << \" pos = \" << pos << \"\\n\";\n    for (ll i = 0; i < sz, ++i)\n        cout << \" arg[\" << i << \"] = \" << arg[i];\n    cout << \"\\n==========\\n\";\n}\n<\/code><\/pre>\n
This will produce something like:<\/p>\n
<Description>\nn = 9 b = 9 x = 9 p = 9\narr[0] = 9 arr[1] = 9 arr[2] = 9 arr[3] = 9 arr[4] = 9\n=========\n<\/code><\/pre>\n
Then pepper your code with calls to this function at many different places, such as:<\/p>\n
ll solve(ll arr[], ll n, ll b, ll x, ll pos) {\n  paxDebug(\"start solve\", arr[], n, n, b, x, pos);\n\n  if(n == b)\n    return n;\n\n  ll idx = pos - 1;\n  for(ll i = n -1; i >= idx; --i) {\n    paxDebug(\"in solve loop\", arr[], n, n, b, x, pos);\n    arr[i + 1] = arr[i];\n  }\n\n  paxDebug(\"after solve loop\", arr[], n, n, b, x, pos);\n\n  arr[idx] = x;\n\n  paxDebug(\"just before solve return\", arr[], n, n, b, x, pos);\n\n  return (n + 1);\n}\n<\/code><\/pre>\n
This should allow you to analyse the values of those variables, an invaluable aid to diagnosing what your issue is.<\/p>\n
\n
And please, for the sake of those who must maintain your code in future (even if it’s you<\/em> six months from now), use better variable names \ud83d\ude42<\/p>\n<\/p><\/div>\n
